Question

Definition of electromagnetic wave in physics

Answer 1

A wave consisting oscillating electric and magnetic field perpendicular to each other and also perpendicular to the direction of propogation of the wave.

Answer 2

Electromagnetic waves are formed by the periodic vibrations of the mutually perpendicular electrical and magnetic fields in a plane normal to the direction of wave propagation ..thus electromagnetic waves are the transverse waves which have speed same as that of light and they can travel through vacuum ....
