Question

Assertion: Sound waves do not travel through the vacuum.

Reason: Sound waves are mechanical waves that require a medium for their propagation.

• A. Both assertion and reason are correct and the reason is the correct explanation assertion
• B. Both assertion and reason are correct but the reason is not the correct explanation assertion
• C. Assertion is correct but the reason is not correct
• D. Both assertion and reason are incorrect

Answer 1

The correct option is A

Both assertion and reason are correct and the reason is the correct explanation assertion

The explanation for the assertion:

1. The sound waves require a medium to propagate.
2. Vacuum has no medium to offer, so sound waves can't travel in vacuum.
3. So, the assertion is correct.

The explanation for the Reason:

1. Sound waves are essentially mechanical waves that need a medium to propagate.
2. These waves vibrate the medium to generate sound.
3. So, the reason is correct.

Thus, both the assertion and reason are correct and the reason is the correct explanation of the assertion.

Hence, the correct answer is option A
