Visible light Sarangan Kathirgamanathan 12V Introduction Visible light is part of the electromagnetic spectrum and like all electromagnetic waves it is a transverse waves which means it moves at right angles to the direction of propagation. It does not need a medium to travel. Visible light is the only part of the electromagnetic spectrum that […]
