Atomic Structure Question 169
Question: Minimum de-Broglie wavelength is associated with [RPMT 1999]
Options:
A) Electron
B) Proton
C) $ CO_2 $ molecule
D) $ SO_2 $ molecule
Show Answer
Answer:
Correct Answer: D
Solution:
$ \lambda =\frac{h}{mv}. $ For same velocity $ \lambda \propto \frac{1}{m} $ . $ SO_2 $ molecule has least wavelength because their molecular mass is high.
