Question:

What is the expression for wavelength of an electron moving under a potential difference of V volts ?

Options:

\(\lambda\) = \(\frac{12.27}{V}\) A°

\(\lambda\) = \(\frac{1.227}{\sqrt{V}}\) A°

\(\lambda\) = \(\frac{12.27}{\sqrt{V}}\) A°

\(\lambda\) = \(\frac{1.227}{V}\) A°

Correct Answer:

\(\lambda\) = \(\frac{12.27}{\sqrt{V}}\) A°

Explanation:

Expression : \(\lambda\) = \(\frac{12.27}{V}\) A°
