Calculate the wave length of an electron moving with a velocity of `2.05xx10^(7)ms^(-1)`.

Options

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

Answer

C

Explanation

`lambda = (h)/(mv) ` i.e. `lambda prop 1/V`
