What are their characteristics ?

❌❌❌No Spamz❌❌❌​

Answer 1

Answer:

An electromagnetic wave(EM wave) is a wave consisting of both electric and magnetic fields acting in perpendicular direction to each other. Waves such as Gamma rays, X-rays, Light, Radio etc.., are all electromagnetic radiations.

characteristics:

• Electromagnetic waves are propagated by oscillating electric and magnetic fields oscillating at right angles to each other.
• Electromagnetic waves travel with a constant velocity of 3×10 −8 ms −1 in vacuum.
• Electromagnetic waves are not reflected by electric or magnetic field.
• Electromagnetic waves can show reflection and refraction just like light waves.

Answer 2

Answer:

hello

In physics, electromagnetic radiation consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum

Characteristic of electromagnetic waves are as follows: -

Characteristic of electromagnetic waves : -(i) They do not require any material medium for their propagation

.(ii) The oscillations of and are perpendicular to each other and are in same phase.

.(iii) They are transverse in nature.

iv) They travel through vacuum with same speed,

hope this helps
