Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.
UV light is typically found as part of the radiation received by the Earth from the Sun. Most humans are aware of the effects of UV through the painful condition of sunburn. The UV spectrum has many other effects, including both beneficial and damaging changes to human health.
How many ultraviolet rays are there?

Ultraviolet rays, or radiation, is a type of electromagnetic waves.
Yes, X-rays and gamma rays have higher frequencies than ultraviolet rays.
no, because ultraviolet rays are just above seeing and with ultraviolet lights, you see a more violet color.
Both Gamma Rays and X Rays have a much high frequency that Ultraviolet Rays.
Ultraviolet rays cannot be seen or felt. Ever had a sun-burn? I say UV rays can be felt.
