Question

All vibrating bodies produce sound.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation -

1. All the moving vibrating bodies do produce sound, but it is just that we human beings are not capable of hearing all the sound produced in the universe.
2. The range of sound that human beings can hear is called the audible range of sound which is from the frequency 20Hz to 20000 Hz.
3. A sound is a form of energy that gives us a hearing experience. We see objects around us with the help of our eyes by detecting light from objects.
4. In the same way, ears are used to detect sound. The sound is produced by the vibration of objects and is propagated through a medium from one location to another. The to and fro or back and forth motion of an object is termed as vibration.
5. The motion of objects causes vibrations. In many cases, we can see the vibrations with our naked eyes. While in some cases their amplitude is so small that we cannot see them but can experience them.

Hence, the given statement is true.
