Dual Nature Of Light Question 354
Question: An electron is accelerated through a potential difference of V volt. It has a wavelength associated with them is.
Options:
A) V volt
B) 1837V volt
C) V/1837volt
D) $ \sqrt{1837} $ V volt
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ \lambda =\frac{h}{\sqrt{2mqV}} $ and mV = constant $ 1837V’=1\times V\text{ or }V’=\frac{V}{1837}volt $
