Question

what are mechanical and electromagnetic waves

Answer 1

Categorizing waves on this basis leads to two notable categories:electromagnetic waves andmechanical waves. Anelectromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space).Electromagnetic waves are produced by the vibration of charged particles.

Answer 2

mechanical waves may be defined as the total produced waves by a plane field.
and electromagnetic waves may be defined as the total surface waves produce by in 1 seconds
