Nature of Waves: Wave Decomposition (Dispersion)
Incident wave decomposition (dispersion) will occur at the time of collection of the wave at the same rate in a medium to propagate in a field boundary so that each experienced a wave refraction at different rates (different refractive indices). So that the collection of the wave will be broken down into each wave.
Thus, if we spread out a group of waves in a medium, then by the time the wave group to the field boundary wave groups in accordance with the direction of wave propagation bias. Events dispersion or decomposition of a wave group can easily be demonstrated easily by a prism.
White light is a wave consisting of a collection of a wide range of wavelengths (ranging from light red to light purple). At the time of white light propagating in the air, the same rate of each wave, which is c. When white light falls on the first boundary of a prism, each wave will be biased by the direction of deflection different because each wave will move inside the prism with a different rate, so that they will break down into each wave. Then, at the time of each wave until the second prism boundary, the direction of the deflection of each wave getting enlarged, so that decomposition becomes increasingly apparent.

Benefits of Ultrasonic Sound
Ultrasonic sound is used as a control tool that bats avoid collisions with objects in front of him, with the bat always emits ultra-sonic waves at the time fly. If bats recapture soniknya ultra sound means there is an obstacle in front of him so he avoided the collision.
b. Ultrasonic sound In the field of health
Ultrasonic waves used in the fields of health in a variety of diagnoses. Pulses of high-frequency ultrasonic waves generated worn directly on the body are diagnosed. Pulse wave reflection occurs when the wave on the boundary of two different network density (eg meat with bones, meat with blood vessels filled with fluid).
Research using ultrasound in the field of health can be to know:
1. The development of the fetus as well as to determine whether or not normal fetal condition.
2. Disorders of the liver, kidney, brain, pancreas, heart vulva vessels.
3. Bleeding in the body to detect its location and can roughly know the lack of blood.
c. Ultrasonic sound In industry
Ultrasound is used to find cracks inside of the metal connection, stirring so that a homogeneous mixture of milk, destroy bacteria in foods preserved in cans.

The Function of the Respiratory Organs
Breathing is the whole process of the cells in an organism in receiving oxygen and release carbon dioxide. Therefore, according to McLaren & Rotundo (1985: 579), breathing can be divided in three forms, namely external respiration (external respiration), internal respiration (internal respiration), and breathing can have several meanings. Breathing can mean just breathe, insert and remove the air from the lungs.
For biologists, breathing is the whole process of the cell in an organism in receiving oxygen and release carbon dioxide. Therefore, according to McLaren & Rotundo (1985: 579), breathing can be divided in three forms, namely external respiration (external respiration), internal respiration (internal respiration), and cellular respiration (cellular respiration).
External respiration is the air exchange that occurs in the lungs. In this process, oxygen into the blood and carbon dioxide is emitted into the atmosphere. Air exchange between the blood and the cells in the body is called internal respiration. Oxygen and carbon dioxide moves opposite. Oxygen diffuses from the blood into the cells. Meanwhile, carbon dioxide diffuses out of the cells to the blood. Cellular respiration is a chemical process that occurs in the mitochondria of cells.
Type – the type of Respiratory Organs
Human respiratory system has the respiratory organs that support the process of breathing. The respiratory organs in structure and function vary. Human respiratory organs consist of the nose, pharynx, larynx, trachea, bronchi, and alveous. How does the structure and function of each of the respiratory organs? Note the following explanation.
a. Nostril Breathing Organ.
The nose is the first breathing apparatus through which the air. The tip of the nose is supported by cartilage and bridge of the nose is supported by the nasal bone. Both nasal bone connects the nasal cavity with the atmosphere to take in air. Nasal cavity composed of epithelial cells plated flat with coarse hairs. The coarse hairs serve coarse dust filter. Nasal cavity composed of epithelial cells that have a ciliated pseudo-plated goblet cells. Goblet cells are the cells that produce mucus that serves to filter dust, dirt attach the nose hair, and regulate breathing air temperature. As the sense of smell, on the roof or the nasal cavity are the olfactory lobes containing cells smell. Air travel into the lungs begins when the air passes through the nostrils. In the nostrils, the air is filtered by the hairs in the nostrils. Air also becomes warmer when passing through the inside of the nasal cavity. In the nasal cavity inside, there is also the nerve endings that can capture the chemicals contained in the air so that we know different kinds of smells. The ends of the olfactory nerve will then send impulses to the brain.
b. Breathing Organ Pharynx
After going through the nasal cavity, the air will pass through the pharynx. The pharynx is the branching between the gastrointestinal tract (esophagus) and respiratory tract (larynx and trachea) with a length of approximately 12.5 to 13 cm. Pharynx consists of three parts, namely the nasopharynx, oropharynx, and laringofaring. The pharynx is a meeting between the respiratory and digestive tract. Therefore, when swallowing food, a valve (epiglottis) will close the airways (glottis) so that the food will go into the digestive tract. In this branch, there is a valve epiglottis which prevents food entering the trachea.
After passing through the pharynx, the air going towards the larynx. The larynx is often referred to as the voice box as it includes the vocal cords. The larynx is a channel that is surrounded by nine cartilage. One of the nine cartilage thyroid cartilage is shaped like a shield. In adult males, the thyroid cartilage is greater than women to form what is called the Adam’s apple.
d. Respiratory Organs Trachea
Of the pharynx, the air passes through the larynx, the vocal cords are located. Of the larynx, air enters the trachea. The trachea is also called “wind pipe” or airways. The trachea has a length of approximately 11.5 cm by 2.4 cm in diameter. The trachea is composed of four layers, namely a layer of the mucosa, submucosa layer, a layer of cartilage, and adventitia layer. Mucosal layer composed of cells of the ciliated pseudo-stratified epithelium containing goblet cells produce mucus (mucus). Cilia and mucus serves to filter dust or dirt entering. Submucosal layer consists of connective tissue. Cartilage layer consists of approximately 18 C-shaped cartilage adventitia layer consists of connective tissue. Tracheal wall lined by ciliated epithelium multilayered false. This epithelium secretes mucus in the trachea wall. This mucus serves to hold foreign bodies in the epithelial cell membrane.
e. Bronchi and bronchioles
After going through the trachea, the channel forked. Both branches are called bronchi. Each bronchial lung connected with the right and left. Bronchi branch out again, smaller branches called bronchioles. Also coated with a layer of bronchial wall layer of cylindrical ciliated epithelial cells. In the vicinity there alveolar capillaries blood vessels. Capillary walls of blood vessels are very close to the alveoli to form a very thin membrane respiration. This thin membrane that allows the diffusion between alveolar air and blood in the capillaries of blood vessels. Bronchi, bronkious, and alveoli form a structure called the lungs.
Bronchioles lead to the alveoli (singular: alveoli), balls shaped structure covered by tiny blood vessels. Flattened epithelium lining the alveoli facilitate blood in the blood capillaries in the oxygen from the air in the alveolar cavity.

Business Strategy Offline Store
Online shop business, of course, is highly developed in this season. Variety of products offered by online stores that most people prefer to shop online than offline. In fact, it is more common abroad, especially in the United States. As for example in jersey bola grade ori increasingly crowded in online but deserted in offline stores resulting in many traders lose money. Almost the online store, about 80% of Americans prefer to shop online rather than offline. Even if some people go offline stores like Best Buy just to check the products and prices, so that they can compare it with the online store.
This offline stores very menrugikan Americans. To attract fans online shopping back to your store, they tried a different strategy. Use the following strategies:
- Create a site as an extension (the store), where customers can choose and order the product. Nevertheless, the goods accepted by the buyer at his shop, which are located close to the buyer to save transport costs are expensive. For example, some retail chains in the XY site, he can take it offline storage XY nearby.
- Improve after-sales service. Some electronics stores, furniture, gadgets, cars and motorcycles provide services call for after-sales service, so customers do not need to transport goods, which must be corrected in the store.
- New services, namely, live, pay and receive. This service allows buyers can leave a shopping list, and then pay for and pick it up when the goods have been received worker.
Strategy – a strategy successfully created, because they know that in developing the business world is not against the current, but the current must be embraced. The above strategy is sure to succeed, because their sales are growing.
But the store is clear – US online retailers such as Amazon do not be silent. Store in the online world can live for activities on the Internet. Amazon also launched a free delivery service to America. Hopefully, this article brings benefits to your offline store. I also felt that way for selling jersey bola that I have elaborated this.
