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
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
Hairdressers typically do not use ultraviolet rays in their services. Ultraviolet rays are more commonly used in tanning beds or sterilization processes in salons, but caution is needed as UV exposure can be harmful to skin and eyes.
Johann Wilhelm Ritter discovered ultraviolet rays
Yes, X-rays and gamma rays have higher frequencies than ultraviolet rays.
Both Gamma Rays and X Rays have a much high frequency that Ultraviolet Rays.
The next name of wavelengths longer than ultraviolet rays is "violet light".
Ultraviolet rays cannot be seen or felt. Ever had a sun-burn? I say UV rays can be felt.
This statement is incorrect. Infrared rays have a longer wavelength than ultraviolet rays. Infrared rays have wavelengths longer than visible light, while ultraviolet rays have wavelengths shorter than visible light.
Sun Rays ^-^
