Class 11 Physics (India) - Hindi: Why do sounds get softer? (Hindi)

Let's think about why sounds would have to get softer as you get further from the source.

Class 11 Physics (India) - Hindi

To help students who prefer to learn by watching Hindi videos, we've created the class 11physics course where the videos are in Hindi but the practice exercises and review articles are in English.

Sound (Hindi)

In these videos and articles you'll see visualizations of the propagation of sound waves, along with a visual definition of a sound wave's amplitude, period, frequency, and wavelength. You'll also learn how the speed of sound depends on the different characteristics of the medium. It will be shown how Mach numbers characterize faster than sound travel and their relationship to sonic booms. Also, you'll learn about the decibel scale, why sounds get softer, and how ultrasound medical imaging works.
