Ultraviolet radiations are produced by hot surfaces
Explanation:
- Ultraviolet rays are from electromagnetic spectrum having wavelength less than 400 n m that is less than the visible range and more than the wavelength of X- rays ( that is why humans cannot see the UV radiations by naked eye)
- Ultraviolet radiations are produced on the hot surfaces like sun it can also be produced at laboratories by mercury lamps etc.
- UV rays consists of photons, so the excess exposure to it may cause sunburn or even skin cancer
- UV radiations have speed equal to speed of light in vacuum as it comes under electromagnetic spectrum
