(i)Light is a form of electromagnetic wave that makes things visible or allows the human eye to see.
(ii)It can also be described as radiation that is visible to the human eye.
(iii)Light contains photons, which are little energy packets.
(iv)Light in a straight line.
(v)Sound moves more slowly than light. The velocity of light is 3x 108 m/s in a vacuum.
(vi)Light moves as a transverse wave that doesn’t require a medium.
(vii)Light can move through space without a physical medium. It can therefore also traverse a vacuum.
