Assertion: Sound waves do not travel through a vacuum.
Reason: Sound waves are mechanical waves which require a medium for their propagation.

A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C. Assertion is correct but Reason is incorrect
D. Both Assertion and Reason are incorrect

Explanation

Solution

The sound wave is a type of mechanical wave. The mechanical waves are the waves which require a medium to transport their energy from one location to the other. Sound is a type of disturbance caused by vibration.

Complete step by step answer:
The sound waves do not travel through the vacuum as the vacuum does not contain any particle, even the sound waves are the mechanical waves which rely on the particle interaction to travel from one location to the other.

The sound waves are categorized as the mechanical waves, because of their nature to depend on the medium’s particle interaction to transfer their energy (to travel from one location to the other).

As the reason statement, “Sound waves are mechanical waves which require a medium for their propagation” is the correct explanation for the assertion statement “Sound waves do not travel through a vacuum”, thus, option (A) is correct.

Additional information:
Mainly there are two types of waves. They are Electromagnetic waves and Mechanical waves.
The electromagnetic waves are the combination of an electric and magnetic field and are capable of travelling through the vacuum, as they do not require any medium to transport their energy. Whereas, the mechanical waves are the wave that makes use of the particles of the medium to transport their energy throughout the location.
Note:
The things to be on your finger-tips for further information on solving these types of problems are: Sound is a disturbance caused by the vibration of objects. For example, A tongue produces vibrations when hit by a rod, then these vibrations give rise to the waves.
