NCERT Solutions : An overview of  Physics Chapter 15

We used a wire as a reference for signifying a wave motion in the NCERT Solutions for Class 11 Physics, and we  learn about the transverse displacement of a wire that is clamped on both sides, and  how to find out the amplitude of a point at a specific distance in the wire. We also  had queries about determining the speed of sound in a wire with pistons at one end and a tuning fork at the other. During competitive tests, these topics are quite significant. Waves is also one of the most significant topics in Physics, and students frequently get questions based on them in various competitive exams.  NCERT Solutions for Class 11 Physics can help you to crack these exams with ease since all these tricky questions have been covered in practice tests, sample papers and the like.

Solving questions about the speed of sound in a steel medium can teach us a lot about waves. There are concerns about how your guitar strings make sound and the frequency of each string on a guitar. We now understand why the pressure antinode of a sound wave is also a displacement node and vice versa. We’ll also learn how a blind dolphin navigates around obstacles in a river and seeks prey. If a man stands at a specific distance from an observer and blows a horn, we can determine the frequency of the horn-based on whether the man is running towards or away from the observer.

A similar example can be  of a truck blowing the horn at a man at a petrol pump, how to find its frequency, speed and wavelength.

Some of the characteristics of waves include: frequency, amplitude, wavelength, phase, resonance, and displacement of waves such as longitudinal and transverse motion in diverse mediums.

The Waves Chapter of Class 11 includes a wide range of topics, including:

  • Waves
  • The nature of waves in various mediums
  • Waves and their qualities are represented graphically
  • Wave by wave comparison
  • Sound velocity
  • A symphony of motion
  • Calculation and resonance between waves
  • Oscillation displacement and velocity

Define Overtone

 It’s an important chapter in Physics. An overtone is a sound frequency that is higher than the fundamental frequency. The term “overtone” is applied to higher-frequency standing waves.

It is a frequency that is typically generated by instruments. Second harmonic is another name for overtone. One of the key advantages of overtone is that it can adapt to any fundamental frequency valuation.

Some of the factors affecting the velocity of sound are:

  • The square root of the density of the particular gas is always inversely proportional to the velocity of the gas.
  • In a gas, the square of the absolute temperature of sound is always directly proportional to its velocity.
  •  Changes in gas pressure have no effect as long as the temperature remains constant.
  • When comparing dry and moist air, the speed of sound velocity is greater in moist air because the density of moist air is less than that of dry air.

There are  different  fundamental properties  in every wave. Reflection, refraction, diffraction, and interference are the four basic properties of waves. Wavelength, frequency, amplitude, and speed are all components of waves. A wave is defined by its amplitude, length, and frequency.

No, Chapter 15 of Physics for Class 11 is not difficult. However, good preparation is essential to perform well on the exam. To take advantage of this, the student must thoroughly study all the chapters and highlight all of the key points so that they may be referred to quickly when needed. They should also develop the practice of taking their own notes so that they can remember the concepts and ideas presented in the chapter. Finally, it goes without saying that students should obtain NCERT solutions and practise sample papers, and model question papers shared with students on a regular basis. Undoubtedly students will be able to get good marks now and perform well in other competitive exams later.
