Ratio of frequency of revolution of electron in the second excited state of `He^(o+)` and second state of hydrogen is

Options

A. `(32)/(27)`
B. `(27)/(32)`
C. `(1)/(34)`
D. `(27)/(2)`

Explanation

To find the ratio of the frequency of revolution of an electron in the second excited state of helium ion (He⁺) and the second state of hydrogen (H), we can follow these steps:

### Step 1: Understand the formula for frequency
The frequency of revolution (f) of an electron in an atom can be expressed as:
\[ f \propto \frac{z^2}{n^3} \]
where:
- \( z \) is the atomic number,
- \( n \) is the principal quantum number (energy level).
