Answer:
1.Electromagnetic waves are formed when an electric field comes in contact with a magnetic field.ultraviolet waves.UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights.
2.Radio Waves-Radio works by transmitting and receiving electromagnetic waves. The radio signal is an electronic current moving back and forth very quickly. A transmitter radiates this field outward via an antenna; a receiver then picks up the field and translates it to the sounds heard through the radio.
3.X-rays-Today's x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. ... When x-rays come into contact with our body tissues, they produce an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them.
