Is absorbing light a chemical reaction?
Light absorption is a physical process; but the effects of the absorption may be chemical.
What are some examples of light absorption?
An example of light absorption is a crystal. Crystals absorb light and then reflect the light back out resulting in the appearance of a rainbow.
What is the first process in the light dependent reactions of photosynthesis?

Absorption mechanism that requires energy?
Active transport
Light absorption by a pigment is measured for red blue green and yellow light what is the dependent and the independent variable?
The light absorption is dependent on the measurement of the red, blue, green and yellow light ( which is the independent variable ).
