Assertion: When a wave travels from a denser medium to rarer medium, then ampltitude of oscillation increases.
Reason: In denser medium, speed of wave is less compared to a rarer medium.

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:
B
`A_t = ((2v_2)/(v_1+v_2))A_i`
If `v_1 gt v_2` or 2 is rarer, then `A_t gt A_i`.
