Dual Nature Of Light Question 352
Question: A particle of mass m is projected from ground with velocity u making angle $ \theta $ with the vertical. The de-Broglie wavelength of the particle at the highest point is -
Options:
A) $ \infty $
B) $ \frac{h}{mu\sin \theta } $
C) $ \frac{h}{mu\cos \theta } $
D) $ \frac{h}{mu} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Velocity at highest point $ ~=usin\theta . $
$ \therefore {\lambda_{D}}=\frac{h}{mu\sin \theta } $ (Since $ \theta $ is velocity wrt vertical)
