What is color absorption and reflection?

Colored objects look the way they do because of reflected light. When sunlight is shined on a green leaf, the violet, red and orange wavelengths are absorbed. The reflected wavelengths appear green. In each case we are seeing the complementary colors to the ones absorbed.

How is a color related to light absorption and reflection?

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.

What does color absorption mean?

If wavelengths of light from a certain region of the spectrum are absorbed by a material, then the materials will appear to be the complementary color Thus, for instance, if violet light with wavelength of 400nm is absorbed, the material will look yellow. If the material absorbs blue you will see the color orange.

What is the definition of absorption of light?

Light absorption is a process by which light is absorbed and converted into energy. Absorption depends on the electromagnetic frequency of the light and object’s nature of atoms. The absorption of light is therefore directly proportional to the frequency. If they are complementary, light is absorbed.

What is meant by absorption of light?

What is absorption pharmacokinetics?

The most important principle in pharmacokinetics theory is drug absorption which is defined as the transportation of the unmetabolized drug from the site of administration to the body circulation system. The bioavailability of a drug product is known as the rate and extent of its absorption.

What does absorb mean example?

Absorb means to soak up. An example of absorb is when a towel takes in water from your body after a bath. verb. Absorb is defined as to take in something and make it part of a larger unit. An example of absorb is a big company that takes over a smaller one.

What is the reflection of light?

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.
