Basic structure of amino acids

  Amphoteric nature.  As indicated by its name, an amino acid has a chemical structure that combines both acid and base (amino) factors.  This important chemical structure gives to amino acids a unique amphteric nature (Gr. amphoteros, both).  This dual nature can be seen in the fundamental pattern of amino acid as shown in the diagrams above.  The acid factor is the carboxyl group (COOH) and the base factor is the amino group (NH2).  A radical that is specific for the individual amino acid is grouped around a central carbon atom. 
  As a result of its dual nature, an amino acid in solution can ionize (dissociate or separate into its constituent ions)  to behave either  as an acid or as a base, depending on the pH of the solution.  This means that amino acids have a great buffer capacity, which is an important clinical characteristic.  The interesting term commonly used for this unique phenomenon is  “zwitterion.”  The term is taken from the German word  Zwitter, meaning “hybrid”, and the Greek word  ion, meaning “wanderer.”  Amino acids behave like “hybrid wanderers,”  either acid or base, depending on the buffering need presented by the particular solution they are in.

Because light travels in both waves and photon packets, it behaves both like a wave and a particle.

Electromagnetic Waves
---------------------
To understand how light travels from the sun to the Earth, you have to understand what light is. Light is an electromagnetic wave--a wave of electric and magnetic energy oscillating very quickly. There are many different electromagnetic waves, and the type is determined by the speed of oscillation. For example, radio waves oscillate more slowly than light, while X-rays oscillate much more quickly. These electromagnetic waves travel in small packets called photons. Because light travels in both waves and photon packets, it behaves both like a wave and a particle.

 ─ Light is an electromagnetic wave--a wave of electric and magnetic energy oscillating very quickly. 
 ─ There are many different electromagnetic waves,
 ─ the type [of electromagnetic waves] is determined by the speed of oscillation.
 ─ For example, radio waves oscillate more slowly than light, 
 ─ X-rays oscillate much more quickly [than light]. 
 ─ Because light travels in both waves and photon packets, it behaves both like a wave and a particle.
 ─ 
 ─ visible light spectrum like sunshine (sunlight) can not go through wall
 ─ radio wave (AM, FM, short wave) can go through wall 
    ─ 
 ─ television signal (another type of wave) can go through wall
    ─ with an inside antenna 
    ─ you can watch television inside your house 
    ─ the reception should be better with an outside antenna 
 ─ 
 ─ sound 

Traveling Through Space
-----------------------
Most waves require a medium to travel in. For example, if you drop a rock in a pond, it makes waves in the water. No water, no waves. Because light consists of photons, however, it can travel through space like a stream of tiny particles. The photons actually travel more quickly through space and lose less energy on the way, because there are no molecules in the way to slow them down.

The Atmosphere
--------------
When light travels through space from the sun, all of the frequencies of light travel in a straight line. When light hits the atmosphere, however, the photons begin to collide with gas molecules. Red, orange and yellow photons have long wavelengths and can travel right through the gas molecules. Green, blue and purple photons, however, have shorter wavelengths, which allows molecules to easily absorb them. The molecules hold onto the photon for only an instant, then shoot them out again in a random direction. This is why the sky looks blue. Many of these scattered photons fly toward the Earth, making the sky appear to glow. This is also why sunsets look red. At sunset, the photons have to travel through a larger layer of atmosphere before they reach your eyes. More of the higher frequency photons are absorbed, leaving layers of red, orange and yellow.

Wave-Particle Duality of Light
The quantum theory of light was given by Einstein, which describes matter, and light consists of minute particles that have properties of waves associated with them. Light consists of particles known as photons and matter are made up of particles called protons, electrons, and neutrons. When all the theories are put together, it can be concluded that light is a particle with wave behaviour. So light is dual in nature.
