Why is Light a Source of Energy

Question

Why is light a source of energy?
A) It excites an electron within a pigment molecule, which then serves as a source of light energy that can be used for work.
B) It excites an electron within a pigment molecule, which then serves as a source of heat energy that can be used for work.
C) It excites an electron within a pigment molecule, which then serves as a source of potential energy that can be used for work.
D) It excites an electron within a pigment molecule, which then serves as a source of kinetic energy that can be used for work.

Accepted Answer

Light excites electrons within pigment molecules, elevating them to a higher energy state. This higher energy state represents potential energy, which can then be converted into other forms of energy to perform work, such as in photosynthesis in plants.
