Explanation:

Electromagnetic waves are waves that do not require or need a material medium for its propagation, but they travel successfully in free space (vacuum). These waves exist with an enormous range of frequencies called the electromagnetic spectrum.

Electromagnetic spectrum is defined as the range of all radiation possessing the special characteristics of electromagnetic waves arranged in order of their wavelength or frequency. The electromagnetic spectrum is made up of radio waves, infrared radiation, VISIBLE LIGHT, ultraviolet rays x- rays, gamma rays.

VISIBLE LIGHT: This is a small spectrum from the enormous range of frequencies of electromagnetic radiation. It provides radiant energy and makes things possible to be seen. The wave ranges from 4.5× 10^-7m to 7.0× 10^-7m. When the visible light is passed through a prism, it disperses into different wavelengths according to the colour make up. Dispersion of visible light produces the colors red (R), orange (O), yellow (Y), green (G), blue (B), (I) indigo and violet (V).

Therefore from the options given, red, Green, indigo and violet are examples of visible light spectrum.
