Question

Sound is produced due to
(A) Friction
(B) Vibration
(C) Circulation
(D) Refraction

Answer 1

Hint :In this question, we need to comment on the reason for the generation of the sound. For this, we will first go through the different terms present in the options and then, choose the correct out of them. Sound is a wave that propagates through a medium and is produced due to the vibration of a body. Using the definition of sound and the definition of each of the given options, we will get the correct answer.

Complete Step By Step Answer:
A friction is a type of force acting between the common surfaces of the two bodies either in motion or in rest.
Flow of the air in the atmosphere in a definite circulatory or random motion is termed to be as Circulation.
Refraction is the phenomenon by which the light can pass through the material. Not all the light rays could be refracted as some of the light rays are reflected back in the original medium.
A sound is produced by the vibrating body. The vibrating body causes the medium such as water, air, etc. around it to vibrate and thus produces sound. Sound is a vibration that propagates an acoustic wave through a transmitting medium such as a gas, liquid or solid.
Option B is correct.

Note :
Students must note that the loudness of the sound depends on the amplitude of the wave, the bigger amplitude of the wave produces louder sound and it can damage the ear. Sound is the vibrations that travel through the air or by any other medium as an audible mechanical wave. Sound can be of different types such as soft sound, pleasant, unpleasant, musical audible and inaudible sounds.
