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

Options

A. two times the de-Brogile wavelength of the electron in the ground state
B. `1//4^(th)` of the de-Brogile wavelength of the electron in the ground state
C. four times the de-Brogile wavelength of the electron in the grounds state
D. half of the de-Brogile wavelength of the electron in the ground state

Answer

C

Explanation

`lambda=h/(mv)=(hn)/(mv_(0)z)`
