what is the source of emf waves?

Answer Posted / guest

The sources of classical electromagnetic waves are
accelerating electric charges. (Note that acceleration
refers to a change in velocity, which occurs whenever a
particle’s speed or its direction of motion changes.) A
common example is the generation of radio waves by
oscillating electric charges in an antenna. When a charge
moves in a linear antenna with an oscillation frequency f,
the oscillatory motion constitutes an acceleration, and an
electromagnetic wave with the same frequency propagates away
from the antenna
