Chapter 8- Electromagnetic Waves!

Comprehensive Course of the Electromagnetic Waves!

Electromagnetic waves are the waves that get created due to the vibration of electric charge. These waves have the capacity to travel even in the outer space without any medium. Multiple concepts associated with the electromagnetic waves are included in the CBSE curriculum of class 12th.

ScoreX™ brings an effective course of Class 12 Physics Ch-8 Electromagnetic Waves.

What do you get in this chapter course?

In the course of the Physics class 12 ncert solutions chapter 8, all the topics associated with the chapter curriculum have been added.

1. Displacement Current

Displacement current doesn’t change the direction, like alternating current. The phase stays the same during the flow of the DC or displacement current.

2. Electromagnetic Waves

Electromagnetic waves have a nature of passing without the need of any medium for the flow. This is why these waves can travel through a vacuum as well. There are several sources of getting electromagnetic waves.

·         Sources of Electromagnetic Waves

·         Nature of Electromagnetic Waves

3. Electromagnetic Spectrum

Multiple waves come under the electromagnetic spectrum. The radio waves, microwaves, infrared, and others are found in the electromagnetic spectrum. The spectrum, having the electromagnetic nature, travels through the space to reach earth. There are multiple benefits of the ultraviolet and X-rays. Various industries including medical get benefited with the use of these waves.

·         Radio Waves

·         Microwaves

·         Infrared Waves

·         Visible Rays

·         Ultraviolet Rays

·         X-Rays

·         Gamma Rays
