A particle of mass m is projected form ground with velocity u making angle `theta` with the vertical. The de Broglie wavelength of the particle at the highest point is

A

`infty`

B

`(h)/(m u sin theta)`

C

`(h)/(m u costheta)`

D

`(h)/(m u)`

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity at highest point`=usintheta`
`lamda_D=(h)/(m usintheta)` (`sintheta` is angle w.r.t. verical)
