The orbital frequency of an electron in the hydrogen atom is proportional to

Options

A. `n^(3)`
B. `n^(-3)`
C. `n^(1)`
D. `n^(0)`

Answer

B

Explanation

Time period of electron , `T = (4 epsi_(0)^(2) n^(3) h^(3))/(mZ^(2) e^(4))`
`therefore T prop n^(3)`
`therefore (1)/("frequency" (f)) prop n^(3)`
or `f prop n^(-3)`
