Question

Assertion (A): An echo is formed due to reflection of sound.

Reason (R): Reflection of sound takes place in the same way as reflection of light waves.

Options

• 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, but Reason is not correct explanation of the Assertion.

Explanation:

Assertion (A) is true. An echo is produced due to the reflection of sound from a distant surface.

Reason (R) is also true. Sound waves obey the same laws of reflection as light waves.

However, the Reason only states how sound is reflected; it does not directly explain the formation of an echo, which also requires the reflected sound to reach the listener after a sufficient time delay.

Therefore, both A and R are true, but R is not the correct explanation of A.
