UV rays are electromagnetic waves have shorter wavelength than that of visible light(10nm to 400nm)
It can cause chemical changes, hence causes many substance to glow
It is non ionizing radiation
It can cause damage to living beings(harmful to humans) and is blocked by ozone layer
It may leads to cancer
It produces heat in surface of earth
Used to prevent counterfeiting
UV rays are used for wireless communication also
