Describe how a photosystem converts light energy to chemical energy

A photon of light is absorbed by a chlorophyll molecule. The photon increases the energy of an electron in the chlorophyll molecule, so the electron is boosted to a higher orbital. This excited state results in a redox reaction, in which the electron moves from the chlorophyll molecule to an electron acceptor, reducing it. The electron acceptor can be various different molecules such as chlorophyll A0.

The speed of  sound:   sound travels  at different speeds depending on what it istraveling through. of the three mediums (gas, liquid, and solid)  sound waves travel the slowest through  gases, faster  through  liquids, and fastest  through  solids.
