NCERT Solutions for class 11 Physics Chapter 15: Waves

NCERT Solutions for Class 11 Physics Chapter 15: Waves deals with the concepts of wave and wave motion. Wave motion is referred to as the energy and momentum movement from one point to another in a medium instead of actually transferring the substances between the places.

Class 11 Physics Chapter 15 Waves is a part of Unit 10 Oscillations and Waves which has a weightage of 10 marks in the Class 11 Physics Examination. The chapter covers concepts of transverse and longitudinal waves, the principle of superposition of waves, and the Doppler effect.

Class 11 Physics Chapter 15 – Concepts Covered

A wave is a disturbance that travels through a material medium as a result of the repeated periodic motion of the particles of the medium about their mean positions without any actual transportation of matter.

The particles of the medium traversed by a wave have relatively small vibrations about their mean positions. However, the particles are not displaced permanently in the direction of propagation of the wave.

Mechanical waves can be propagated or produced only in a material medium.

These waves work on Newton’s laws of motion. For example, waves on strings, waves on the water surface, sound waves etc.

Electromagnetic Waves are waves that do not require any material medium for their production and propagation. They can pass through a vacuum or any other material medium.

Some examples of electromagnetic waves are visible light, ultraviolet light, microwaves, radio waves, etc.

Wave velocity is the time rate of propagation of wave motion in a given medium. It depends upon the nature of the medium.

Wave velocity (υ) = frequency (v) x wavelength (λ)

Matter waves are associated with moving particles of matter, like protons, electrons, neutrons etc.
