The absorption of light by atoms or molecules depends on the energy state of its electrons. These energy states are determined by:
- the charge of the nucleus
- the particular orbitals that the electrons have filled
- the particular orbitals that the electrons have been excited to
- the particular bonds and/or hybridized orbitals the electrons have been forced into.
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.

When chlorophyll molecules asbosrb light?
It is in the light dependant reaction. Thew first step of the photosynthesis.
What are the molecules in plant cells that absorb light energy?
Chlorophyll.
What are some molecules that absorb short wavelength light in the atmosphere?
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
What molecules embedded in the thylakoid membranes absorb light energy?
The Chlorophyll
What gases in the atmosphere absorb infrared radiation and Which gases absorb ultraviolet?
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).
What determines how well light passes through an object?
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
Why does black absorb sunlight?
Black absorbs sunlight because it contains pigments that absorb a wide range of wavelengths of light, including those in the visible and near-infrared spectrum. This absorbed light energy is then converted into heat, which raises the temperature of the black object.
What do chlorophyll molecules absorb?
light.
What molecules absorb light?
All molecules will absorb light to a greater or lesser degree
What molecules that absorb specific wavelengths of light?
Chlorophyll and carotenoids are examples of molecules that absorb specific wavelengths of light for photosynthesis in plants. In the field of medicine, hemoglobin and melanin are molecules that absorb specific wavelengths of light for various diagnostic and therapeutic purposes.
How does Rayleigh scattering fluorescence contribute to the phenomenon of light scattering in the atmosphere?
Rayleigh scattering fluorescence is a process where molecules in the atmosphere absorb and re-emit light, causing the scattering of light in different directions. This phenomenon contributes to the overall scattering of light in the atmosphere, which is why the sky appears blue during the day.
What color of light is scattered the most by the molecules in Earth's atmosphere?
Blue light is scattered the most by the molecules in Earth's atmosphere.
What are colored molecules that absorb light?
Colored molecules that absorb light are usually organic compounds that contain conjugated double bonds or transition metal ions in their structure. These molecules absorb specific wavelengths of light, causing them to appear colored. The absorption of light by these molecules leads to the excitation of electrons to higher energy levels.
What molecules in chloroplasts can absorb light?
Chlorophyll a and chlorophyll b are the main molecules in chloroplasts that can absorb light for photosynthesis. These pigments absorb light energy and convert it into chemical energy, which is used to drive the process of photosynthesis.
Why are certain colors absorbed into some objects but not others?
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.
When chlorophyll molecules asbosrb light?
It is in the light dependant reaction. Thew first step of the photosynthesis.
Why does an orange look orange and and an apple look red?
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.
