Question

Problem 2

Answer 1

Given information

 sound wave is EM wave or not.

Step-by-step explanation

Step 1.

Electromagnetic waves are waves which are created due to vibrations between an electric field and a magnetic field. In electromagnetic wave electric field, magnetic field and direction of wave propagation are perpendicular to each other. Electromagnetic does not need a medium to propagate since energy in an electromagnetic wave is contained in magnetic and electric field.
