(a) How are electro-magnetic waves produced ? Depict an electromagnetic wave propagating in Z-direction with its magnetic field oscillating along X-direction.
(b) Write two characteristics of electro-magnetic waves.
a) When a charged particle oscillates with some frequency, so, it produces an oscillating electric field in space which further produces an oscillating magnetic field and thus, in turn, is a source of electric field and this process goes on and hence, an electromagnetic wave propagates in the space.
b)
