Q. What do you understand by electromagnetic waves ?
:- Electromagnetic waves are coupled electric and magnetic oscillations that moves with the speed of light and exhibit typical wave behavior , i.e.
(a) they travel with speed of light
(b) they are transverse in nature
(c) the ratio of electric to magnetic field vector in an electromagnetic wave equals to the speed of light
(d) they carry both energy and momentum
