Topics of Chapter 14 NCERT Solutions for Class 11 Physics

Following are the topics in chapter 14 The Waves Chapter of Class 11

• Introduction

• Transverse and longitudinal waves

• Displacement relation in a progressive wave

• The speed of a travelling wave

• The principle of superposition of waves

• Reflection of waves

• Beats

• Doppler effect

Waves are connected with rotating electrons, protons, neutrons and other basic particles. Waves are also related to molecules and atoms. The chapter explains many features of a wave, and its characteristics like frequency, amplitude, wavelength, phase, resonance and wave displacement.

The waves are in so many forms like sounds, lights, radio signals and microwaves. This chapter 14 of Waves Class 11 NCERT solutions has many detailed sections as well, which are also important for engineering and college admission entrance tests. The chapter will next teach students about the idea of wave motion.

Our expert team of teachers has designed the syllabus according to the latest guidelines of NCERT and CBSE.

Introduction

In this chapter 14 class 11th we will learn about waves and its motion.  The disturbances produced in air are much less obvious and only human ears or a microphone can detect them. These patterns, which move without the actual physical transfer or flow of matter as a whole, are known as waves. 

Further we will learn what sound is, how it produces, and what is the behaviour of sound. What is the transverse wave and Longitudinal wave?

Transverse And Longitudinal Waves

In this topic we will learn about types of waves with different examples in detail. Transverse waves formed the medium to move perpendicular to the direction of the wave. Longitudinal waves formed the medium to move parallel to the direction of the wave.

Further in this topic we will learn about waves on the water surface. There are mainly 2 types of waves on water

1. Capillary waves and

2. Gravity waves.

Displacement Relation In A Progressive Wave

In this topic we will see the displacement relation of waves. We will learn some formulas and derivations with the help of examples. In order of this topic we have some other topics like: Amplitude and Phase, Wavelength and Angular Wave Number, Period, Angular Frequency and Frequency and these topics are explained with derivation. 

The Speed of a Travelling Wave 

Wave speed is the distance a wave travels in a particular amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the following equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are already known.

After that we will learn the speed of a transverse wave on a stretched string and Speed of a Longitudinal Wave With various numbers .examples.

The Principle of Superposition of Waves

In this chapter we will learn about the principle of superposition of waves. The principle of superposition of waves tells us about when two or more waves overlap in space, the net resulting disturbance is equal to the algebraic addition of the individual disturbances of the respective waves. When two or more waves move through a same medium, they are likely to interact.

Reflection of Waves

If a wave collides with the wall it also bounces back with some changes in it. If the wave collides with a rigid boundary its phase changes but  if the wave collides with a flexible boundary it will be in the same phase so this is called reflection of the wave.

Frequently Asked Question 

Question 1 : what are the topics in chapter 14 waves

Answer : Following are the topics of chapter 14:

• Introduction

• Transverse and longitudinal waves

• Displacement relation in a progressive wave

• The speed of a travelling wave

• The principle of superposition of waves

• Reflection of waves

• Beats

• Doppler effect

Question 2  What is a transverse wave motion?

Answer : A transverse wave motion is where the particles of the medium are seen to vibrate at right angles or 90 degree towards the direction that the wave propagates. Following are some examples of these are electromagnetic waves, waves on a string and surface water waves. It is to be noted that in the case of the electromagnetic wave, the disturbance caused is not the result of the vibration that the particles produce but also  the result of the oscillation that occurs in the electric and magnetic fields taking place at right angles to the direction in which the wave travels.
