What’s the wavelength for the visible region in electromagnetic radiation?

What’s the wavelength for the visible region in electromagnetic radiation? Correct Answer 400 – 750 nm

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.
