They travels in the form of waves and are filtered through the Earth's atmosphere.
Aside from all the radio signals generated by Man, the Earth radiates primarily in the Infrared portion of the electromagnetic spectrum. This consists of reflected and re-radiated solar heat and 'black body' radiation from the Earth itself. (The reflected radiation includes some components of shorter wavelength such as visible light, but the re-radiated component is essentially all infrared.)
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
ultraviolet radiation
The strongest electromagnetic force on Earth is found between the North and the South Poles. The source of the force is found in the core of the Earth, which is rotating slightly faster than the Earth's own rotation, creating a generator of immense proportions.

ultraviolet rays
Ultraviolet waves
ultraviolet rays are absorbed by the earth changing the rays to heat
Electromagnetic energy of every kind. This includes light, heat, ultraviolet, gamma rays, x-rays and every possible frequency of electromagnetic radiation.
Ultraviolet radiation is blocked by the ozone layer in the lower stratosphere. It blocks 97â??99% of the Sun's UV rays, preventing them from damaging life on the surface of the planet.
They travels in the form of waves and are filtered through the Earth's atmosphere.
The ozone layer. It protects from ultraviolet.
The Sun's energy is transmitted by electromagnetic radiation, with most of the heat caused by ultraviolet radiation striking the Earth's surface. This heat is re-radiated by infrared radiation.
Waves of heat and light, called radiation, travel to earth.
