Ultraviolet.
This is the ultraviolet light.
Ultraviolet Radiation!
Yes, it does. UV-C wavelength is 200-280 nanometers, UV-B is 280-320 nm, and UV-A is 320-400nm.
Ultraviolet has a shorter wavelength than red, green, or infrared light.
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
We know that ultra-violet light, X-rays and gamma rays have higher energy (higher frequency and shorter wavelengths) than visible light.
The wavelength of violet light is shorter.
I assume by light rays, you mean visible light rays. In this case, gamma rays have shorter wave lengths.
because the light is shorter
Violet light has a higher frequency than red light by roughly a factor of 2.
Hotter stars flow with light that is more intense at shorter wave lengths. The hottest stars emit their radiation in short violet light wavelengths. Their light appears blue white when observed.
The violet light has more energy than the red light. Red light is lower on the electromagnetic spectrum, meaning it has a lower frequency (or longer wavelength). You'll recall the colors of the rainbow as red, orange, yellow, etc., and these are the colors going up the frequency spectrum. Photons higher on the spectrum are higher in frequency and energy.
