there is no answer and there never will be
ultraviolet rays, X-rays, and gamma rays would all do that
electromagnetic radiation
All travel at the same speed through a vacuum
All wavelengths used for communication are longer than all infrared, visible, ultraviolet, and X-ray wavelengths.
X-rays have the shortest wavelength of those listed.
Ultraviolet rays
How many ultraviolet rays are there?
Ultraviolet (UV) waves can be used to kill bacteria, but are also harmful to humans. X-Rays are used to analyze bones etc
Bees can see ultraviolet rays.
Protection from Ultraviolet rays/sunlight

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.
