You cannot see ultraviolet rays, you can only see electromagnetic waves that are within the visible light spectrum; therefore it does not have a color. It is simply referred to as ultraviolet because its respective band on the EM spectrum lies above our visible violet frequencies.

uv ray dude
All visible wavelengths are longer than the wavelength of ultraviolet.
A ultraviolet ray contain heat which makes you tanner. Thank you <3
yes
UV (Ultraviolet)
Ultraviolet rays have more energy and a higher frequency, while an Infrared ray is essentially heat, which has less radiation, and a longer wavelength. Also, they are located lower of the Electromagnetic Spectrum.
The wavelength of the x-ray is shorter.
Heat
The sun has a ray called the Ultraviolet ray. The sun is just astar closest to Earth.
