Assertion: A vibrating tuning fork sound...

Assertion`:` A vibrating tuning fork sounds louder when its stem is pressed against a desk top.
Reason `:` When a wave reaches another denser medium, part of the wave is reflected.

A

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

B

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

C

Assertion is true but the Reason is false.

D

both,Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
On pressing the stem agains a desk top, sound becomes louder, because area of vibration increases. The given reason though true is not a correct explanation of the assertion.
