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 $
