Which of the following expressions imposes the condition of quantization of energy of an electron in an atom ?

A

`E = mc^(2)`

B

E = h v

C

`lambda = (h)/(m v)`

D

`m v r = (nh)/(2pi)`

Text Solution

Verified by Experts

The correct Answer is:
D
The electron can move in only those circular orbits where angular momentum (mvr) is a whole number multiple of `h//2pi` i.e., `mvr = (nh)/(4pi)`.
