Question

Assertion (A): One cannot hear a bomb explosion on the moon.

Reason (R): There is no atmosphere on the moon, hence the sound produced due to explosion cannot be transferred.

विकल्प

• If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

• If both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

• If Assertion is true, but the Reason is false.

• If Assertion is false, but the Reason is true.

Answer 1

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

Explanation:

Assertion (A) is true. A bomb explosion on the Moon cannot be heard through the surrounding space.

Reason (R) is true. Sound requires a material medium for propagation. Since the Moon has no atmosphere, the sound produced by the explosion cannot travel through the surrounding space.

Therefore, both A and R are true, and R is the correct explanation of A.
