Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmiting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.

Hi..
The electromagnetic waves are produced by accelerated changes and do not require any material medium for their propagation
(ii) The oscillation of the fields E→ and B→ are in same phase and their direction are perpendicular to each other .
An electromagnetic wave transport linear momentum as it travels through space .
If an electromagnetic wave transfer a total energy u to a surface time t, then total linear momentum delivered to the space is P=uc..
If the wave is totally reflected , the momentum delivered will be 2uc because the momentum of the wave will change from p to -p..
Hope this helps u!!
