April 8, 2025NCERT Solutions for Class 9 Science Chapter 12 Sound: NCERT Solutions go a long way in helping students learn and practice the topics covered in Class 9 Science Chapter 12 Sound. In this article, we have provided the NCERT Solutions of this chapter in PDF format to help students with detailed solutions for in-text questions.
The solutions will help students clear the various concepts covered in the chapter. The in-text and exercise questions are solved in a step-by-step manner as per the latest guidelines. Embibe also offers access to over 2630 questions from 73 different books to help students get additional practice for their exams. Scroll down for all the details pertaining to NCERT Solutions for Class 9 Science Chapter 12 Sound.
In this chapter, the various concepts related to sound are explained with the help of practical activities, examples, and diagrams. Students will learn how sound is produced followed by the propagation of sound. They will also learn two most important aspects with respect to the transmission of sound – sound needs a medium to travel and sound waves are longitudinal waves. The chapter also covers important characteristics of sound waves (frequency, amplitude, and speed) and the speed of sound in different mediums.
Other concepts like the reflection of sound, echo, reverberation, etc. will be explained. Practical applications, like uses of multiple reflections of sound, application of ultrasound, SONAR, etc. will also be discussed.
We have also provided the list of important topics covered in NCERT Class 9 Science Chapter 12 in the table below for students to refer to:
Section | Topic Name |
---|---|
12.1 | Production of Sound |
12.2 | Propagation of Sound |
12.3 | Reflection of Sound |
12.4 | Range of Hearing |
12.5 | Applications of Ultrasound |
12.6 | Structure of Human Ear |
We have provided some important points that are covered in NCERT Class 9 Science Chapter 12 to help students in their exam preparations. Refer to the list below:
Students can check all the important points to remember from NCERT Class 9 Science Chapter 12 Sound on Embibe for.
Students can download the NCERT Solutions for Class 9 Science from the following:
Ans: Class 9 plays a fundamental role in further studies. The only key to score good marks in the CBSE Class 9 Science exam is via consistent practice.
Ans: The class 9 Sound chapter covers all the topics of sound and its applications in brief. To get better at the topics and eventually score good marks, students should read the chapter thoroughly from the NCERT book. Then they must try to solve the questions on their own.
