Generation, propagation and detection of electromagnetic waves is the basis of
The correct option is C radio and television
The communication and broadcasting following
the base on generation, propagation, and detection of electromagnetic waves.
The electromagnetic spectrum describes a
different range of electromagnetic waves. These EM waves are a special type of
wave that can travel without a medium.
Electromagnetic waves are named like
this due to the fact that they have both an electric and a magnetic component.
In a vacuum, EM waves always travel at the same speed i.e. the speed of light.
So, other EM waves besides light are infrared, ultraviolet, radio waves, and
microwaves. Therefore radio and television both are based on EM wave
properties. Other options like lasers, reactors, and computers are not guided
by EM waves.
Thus the correct option is C.
