Assertion: If we see the oscillations of a stretched wire at higher overtone mode, frequency of oscillation increases but wavelength decreases.
Reason: From `v=f lambda, lambda prop 1/f` as `v` = constant.

A

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

B

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

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`f= eta(v/(2l))`
As `eta` increases, frequency increases. Hence, lambda
decrease.
