NCERT Solutions for Class 8 Physics Chapter 13

Toppr app presents the NCERT Solutions for Class 8 Physics Chapter 13 Sound in a very systematic, exhaustive and practical way. Different experiments will help them to grasp the concept for better utilization in solving the problems and doing their homework.

Let us discuss the sub-topics in detail.

13.1: The sound is Produced by a Vibrating Body:

The student will see by experiments that a vibrating object produces sound. In many cases, the vibrations are easily visible to us. But mostly their amplitude is so small that we cannot see them. However, we can feel them easily.

13.2: Sound Produced by Humans:

We, humans, produce the sound by the voice box or the larynx. When the lungs force air through the slit then the vocal cords vibrate and therefore produces sound.

13.3: Sound Needs a Medium of Propagation:

The student will learn that sound needs a medium to travel. When the air has been removed completely then it is said that there is a vacuum and hence sound cannot travel through a vacuum. So, the medium is a must for the propagation of sound.

13.4: We Hear Sound through Our Ears:

Human beings can hear the sound by their ears. In this topic, the student will study the shape and structure of human eardrum. Also, they can understand the process of hearing.

13.5: Amplitude, Time Period and Frequency of a Vibration:

Sound is a wave, so it creates vibration in the medium. So it also has some physical parameters like amplitude, time period and frequency to find details about sound.

13.6: Audible and Inaudible Sounds:

Sound waves can be audible or inaudible for human. This fact depends on the frequency of sound generated.

13.7: Noise and Music:

We know that unpleasant sounds are called a noise but the musical sound is one which is pleasing to our ear.

13.8: Noise Pollution.

The student will study the presence of excessive or unwanted sounds in the environment is harmful and called noise pollution.
