Question

The de-Broglie wavelength associated with the electron in the n = 4 level is :

Options

A.1/4th of the de-Broglie wavelength of the electron in the ground state.
B.four times the de-Broglie wavelength of the electron in the ground state
C.two times the de-Broglie wavelength of the electron in the ground state
D.half of the de-Broglie wavelength of the electron in the ground state

Solution

De-Broglie wavelength of electron
λ =         V ∝ 1/n
λ ∝ n
λ4 = 4λ1
∴  option (2)
