Answer» Right CHOICE is (a) 400 – 750 nm To elaborate: Electromagnetic spectrum is made up of various electromagnetic radiation. They are radio waves, X-RAYS, GAMMA rays, UV rays, the visible region, IR waves, and microwaves. Visible rays are the only ones which a HUMAN eye can see. They range from 450 – 750 nm.
