A particle of mass 'm' is projected from ground with velocity u making angle `theta` with the vertical. The de-Broglie wave length of the particle at the highest point is:

A

`oo`

B

`h/(m u sin theta)`

C

`h/(m u cos theta)`

D

`h/(m u)`

Text Solution

Verified by Experts

(C) velocity at highest point `= u sin theta`.
`:. lambda_(d)=h/(m u sin theta)` (Since `theta` is angle between velocity and vertical)
