Red, orange, yellow, green, blue, violet.

Red.

The flame test is used for the identification of different metals in salts.

Microwaves.

X-rays.

Visible light has wavelengths approximately between 400 nm (violet) and 700 nm (red).

Gamma rays are high-energy electromagnetic waves with very short wavelengths, used in medical treatments and imaging.

Infrared waves are used in thermal imaging and remote controls, and they can be felt as heat.

Ultraviolet rays have shorter wavelengths than visible light and can cause sunburn.
