Photosynthesis: Properties of Light. Slide 2 Visible light is a small part of the electromagnetic spectrum that includes X-rays, microwaves and radio waves. It appears white to us but is actually a combination of light at different wavelengths. This is evident when we see a rainbow or pass light through a prism.

Photosynthesis reverses the direction of electron flow. Water is split and electrons are transferred with H+ from water to CO2, reducing it to sugar. Because the electrons increase in potential energy as they move from water to sugar, the process requires energy. The energy boost is provided by light.
