Assertion : y-x graph of a transverse wa...

Assertion : `y-x` graph of a transverse wave on a string is as shown in figure. At the given instant point `P` is moving downwards. Hence, we can say that wave is moving tiwards positive `y-direction.
Reason : Partial velocity is given by
`vp = -v(dely)/(delx)`

A

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

B

If both Assertion and Reason are true but the Reason is not correct expanation of the 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:
D
IN `vp = -v(dely)/(delx)`,
`vp` is negative and `(dely)/(delx)`(the slope) is also negative.
Hence, the velocity `v` should also be negative.
