The wave - length of a moving electron- - Vidyadip

MCQ

The wave - length of a moving electron-

A
Increases with the increase of the velocity of the electron
B
Does not depend upon the velocity of the electron
✓
Decreases with the increase of velocity of the electron
D
Is equal to zero

✓

Answer

Correct option: C.

Decreases with the increase of velocity of the electron

c
Wavelength of electron varies as: $\lambda=\frac{ h }{ mv }$

Wavelength of an electron is inversely proportional to its velocity. Hence, as velocity increases wavelength decreases.
