NCERT Solutions for Class 11 Physics Chapter 15 Waves

 

Let us start reading the preparation article Regarding CBSE 11 Class

NCERT Solutions for Class 11 Physics Chapter 15 Waves: If you drop stones in still water you can see outward moving circles from the point were water surface is disturbed. Now if you put some cork piece on the disturbed surface you can observe that cork piece moves up and down but not out away from the centre of the disturbance. This shows that the movement of water does not transfer any matter. These patterns, which move without the actual physical transfer of matter are called waves. In NCERT Solutions for Class 11 Physics, you will study about  Chapter 15 Waves. The waves such as waves on a string, sound waves, etc, come under the mechanical waves. These waves require a medium for propagation.  

Electromagnetic waves (you will learn later in your class 12 Physics) do not necessarily require a medium that is they can travel through a vacuum. Light, radio waves, X-rays, are examples of electromagnetic waves and they travel in a Vacuum at a speed equal to the speed of light. The third kind of wave is Matter waves. They are associated with constituents of matter: electrons, protons, neutrons, atoms and for example molecules matter waves associated with electrons are employed in electron microscopes. In this NCERT Solutions for Class 11 Physics Chapter 15, you will study the mechanical waves, which require a medium for their propagation. The NCERT solutions will help you to understand the concepts of this chapter. The main topics of the NCERT Solutions for Class 11 Physics Chapter 15 Waves are listed below

15.1 Introduction

15.2 Transverse and longitudinal waves

15.3 Displacement relation in a progressive wave

15.4 The speed of a traveling wave

15.5 The principle of superposition of waves

15.6 Reflection of waves

15.7 Beats

15.8 Doppler effect

In this NCERT Class 11 Physics Chapter 15 Waves, you will study about mathematical and physical aspects of the longitudinal, transverse and physical wave. In both board exam and competitive exam point of view beats and the Doppler effect is an important topic.

The NCERT Solutions for Class 11 Physics Chapter 15 Waves are given below:

Q 15.1 A string of mass 2.50 kg is under a tension of 200 N. The length of the stretched string is 20.0 m. If the transverse jerk is struck at one end of the string, how long does the disturbance take to reach the other end?
