The absorption of light by atoms or molecules depends on the energy state of its electrons. These energy states are determined by:
For each of these energy states there is a whole forest of higher energy states that a particular frequency of light can further promote them up to. Once promoted to a higher energy state the electron can then 'cascade down' through all the intermediate energy states radiating off quantum of lower frequency light that is dependent on the energy difference of these states.
Some of the gases found in our atmosphere which absorb infrared light are: carbon dioxide, methane, and water vapor. Gases found in our atmosphere which absorb ultraviolet light are ozone (O3) and oxygen gas (O2).
It is in the light dependant reaction. Thew first step of the photosynthesis.
Chlorophyll.
The Chlorophyll
actually the water molecules have the tendency to absorb the EMW waves of a certain frequency normally called to be infrared rays of a wave length below micro waves this the reason for occurrence of green house effect in earth greater this effect leads to global warming
Bonds in molecules absorb light, In black the bonds absorb a lot of visible light frequencies. As black only reflects few frequencies of visible light. it gains it black colour.
1. The configuration of the atoms or molecules in the medium 2. The composition of the atoms or molecules (the configuration of their orbitals, which determines what frequencies of light they can absorb) 3. Magnitude of the vibration of the atoms or molecules in the medium
light.
chloroplast's absorb light energy
colors are different frequencies of light. atoms in objects vibrate in specific frequencies too. objects with atoms vibrating in the frequency corresponding to the color absorb that color and reflect the other frequencies they can't absorb. the color of an object is basically the frequency of light that it can't absorb.
pigment
All molecules will absorb light to a greater or lesser degree
A type of plastids called chloroplasts absorb the light.

The colors that we call orange or red are particular frequencies of visible light. An object that reflects mostly the light in a particular frequency will "look" that color. It is the compounds in the skins of fruits that absorb and reflect light in different frequencies, In the case of the apple, the compounds inside the skin absorb a completely different range of frequencies, and are therefore a different color.* Objects that absorb almost all colors of light appear brown or black. Those that absorb little light of any frequency appear white.
