Question

Given two characteristics of EM waves.

Answer 1

Hint – Here you need to know that EM waves are electromagnetic waves which are the combination of electric and magnetic fields. With each wave of the same speed but of different frequency and wavelength.

Complete step-by-step answer:

Characteristics of electromagnetic waves:

(1) Electromagnetic waves are transverse in nature because they propagate through varying electrical and magnetic fields, so that they are perpendicular to each other.

(2) Propagation of electromagnetic waves shall not require any material medium to travel.

Note – You need to know the different frequency and wavelength of seven types of electromagnetic waves. The waves which have higher frequency have lower wavelength and vice-versa. Some of the common electromagnetic waves are radio-waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, gamma rays. Knowing this will help you a lot in the questions related to EM waves.
