Atomic Structure Question 403
Question: The de Broglie wavelength of a tennis ball of mass 60 g moving with a velocity of 10 metres per second is approximately
Options:
A) $ {10^{-31}} $
B) $ {10^{-16}} $
C) $ {10^{-25}} $
D) $ {10^{-33}} $
Show Answer
Answer:
Correct Answer: D
Solution:
- $ \lambda =\frac{h}{mv}=\frac{6.6\times {10^{-34}}}{60\times {10^{-3}}\times 10}={10^{-33}}m $
