Question

The frequency of revolution of the electron in Bohr’s orbit varies with \( n \), the principal quantum number as:

• A. \( \frac{1}{n^3} \)
• B. \( \frac{1}{n^4} \)
• C. \( \frac{1}{n} \)
• D. \( \frac{1}{n^2} \)

Hint:

For Bohr’s model, remember that the frequency of revolution decreases with the cube of the principal quantum number \( n \).

Answer 1

The Correct Option is A

The frequency of revolution is inversely proportional to \( n^3 \), as the energy of the electron in Bohr’s model depends on the quantum number \( n \).
