 # HC Verma Solutions Vol 1 Chapter 15 Wave Motion and Waves on a String

HC Verma Solutions Vol 1 Chapter 15 Wave Motion and Waves on a String consists of answers to all the major questions which are found in the HC Verma book and those questions that are frequent in competitive exams. Some of the questions are related to the principle of superposition and amplitude amongst others. In order to help students understand the concepts clearly as well as learn the right answers, we are offering a comprehensive set of HC Verma Solutions for class 11 physics. The solutions will help students understand the topics of wave motion more clearly. However, some of the problems given in the chapter include:

• There are questions that require students to find the velocity of transverse vibration when an object is suspended from a rigid support.
• Questions are based on topics like centrifugal force, tension, rectangular and horizontal components of force, angular velocity and linear velocity, etc.
• Students will also solve questions on wave speed, acceleration, spring constant, deflection and mass per unit length of strings.

The solutions to these various questions have been prepared by our experts and will help each student to understand the questions in a better way. Every solution has a fresh approach and further offers full coverage of physics topics and questions that students need to practice for exams like JEE and others.

Students also get to learn about important topics like;

1. Wave Motion
2. Wave Pulse on a String
3. Sine Wave Travelling on a String
4. The velocity of a Wave on a String
5. Power Transmitted along the String by a Sine Wave
6. Interference and the Principle of Superposition
7. Interference of Waves Going in the Same Direction
8. Reflection and Transmission of Waves
9. Standing Waves
10. Standing Waves on a String Fixed at Both Ends (Qualitative Discussion)
11. Analytic Treatment of Vibration of a String Fixed at Both Ends
12. The vibration of a String Fixed at One End
13. Laws of Transverse Vibrations of a String: Sonometer
14. Transverse and Longitudinal Waves
15. Polarization of Waves

## Important Questions In Chapter 15

1. A string fastened to a clamp vibrates in its fundamental mode. Can any position on the string be touched without causing a disturbance in the motion? What will the outcome be if the string vibrates in its first overtone?

2. Which of the given options below are a mechanical wave?

(a) Light waves (b) X-rays (c) Sound waves (d) Radio waves

3. There are two waves of equal amplitude A and equal frequency travelling in the same direction across a medium. What will the amplitude of the resultant wave be?

(a) A (b) 0 (c) 2A (d) Somewhere between 0 and 2A.

4. If we take a tuning fork with frequency 480 Hz and used it to move or vibrate a sonometer wire having natural frequency 240 Hz. Can you pinpoint at which frequency will the wire vibrate?

(a) 720 Hz (b) 480 Hz (c) 240 Hz (d) There is no vibration caused.

5. A transverse wave is travelling along the Z-axis. Can you tell in which axis will the particles of the medium move?

(a) along the Y-axis (b) along the Z-axis (c) along the X-axis (d) It will move in the X-Y plane.
