- It is as if a photon is released by the first excited molecule, which then is absorbed by an electron in a second molecule to excite it to the same excited state. However, no photon is involved in the energy transfer. In this fashion, energy is transferred from one chlorophyll to another.

Light absorption is the process in which light is absorbed and converted into energy. When electrons absorb energy, they become ‘excited’ and move to higher energy levels which are further away from the nucleus.
What Happens When Light is Absorbed? A Quick Overview of Light Absorption. In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.

Atoms and molecules contain electrons. It is often useful to think of these electrons as being attached to the atoms by springs. The electrons and their attached springs have a tendency to vibrate at specific frequencies. Similar to a tuning fork or even a musical instrument, the electrons of atoms have a natural frequency at which they tend to vib...
Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating. But instead of vibrating in resonance at a large amplitude, the electrons vibr...
The color of the objects that we see is largely due to the way those objects interact with light and ultimately reflect or transmit it to our eyes. The color of an object is not actually within the object itself. Rather, the color is in the light that shines upon it and is ultimately reflected or transmitted to our eyes. We know that the visible li...
In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon 's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy). [1]
Glucose and oxygen are used to release energy that organisms need to live. Reactions that absorb energy: Photosynthesis absorbs energy from sunlight, allowing plants to make glucose and...
Simply stated, light is nature's way of transferring energy through space. We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember-- light is energy. Light travels very rapidly, but it does have a finite velocity.
Photosynthesis occurs in chloroplasts found within cells. It is the chloroplasts that contain the green pigment chlorophyll which absorbs light.
