NCERT Solutions for Class 11 Physics Chapter 15 Waves
NCERT Solutions for Class 11 Physics Chapter 15 Waves: For the preparation of class 11 exam and competitive exams like NEET and JEE Mains, solutions of NCERT class 11 chapter 15 waves are helpful. 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 or 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. The waves such as waves on a string, sound waves, etc, come under the mechanical waves. These waves require a medium for propagation. The CBSE NCERT solutions for class 11 physics chapter 15 waves discuss questions based on mechanical waves. Electromagnetic waves (discussed in class 12 NCERT) 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 etc. For example molecules matter waves associated with electrons are employed in electron microscopes. NCERT solutions for class 11 physics chapter 15 waves help in understanding the formulas studied in the chapter. The NCERT solutions will help you to understand the concepts studied in respective chapters.
The main topics of the chapters are listed below
15.2 Transverse and longitudinal waves
15.3 Displacement relation in a progressive wave
15.4 The speed of a travelling wave
15.5 The principle of superposition of waves
15.6 Reflection of waves
15.8 Doppler effect
