FT 1-Light form of energy invisible to the human eye.
FT2- Sunlight energy can convert into storable form.
FT3 -Reflected ray is the ray of light that going towards the surface.

FT6- When light travels from medium to another its velocity and frequency change
but its wave length remains constant.

degree.
