NEET Physics Bohr Model MCQ Question
What is the frequency of revolution of an electron in the first Bohr orbit of a hydrogen atom given the electron velocity is 2.2 × 10^6 m/s and the orbit radius is 5.3 × 10^-11 m?
6.6 × 10^15 Hz
3 × 10^15 Hz
1 × 10^16 Hz
4 × 10^16 Hz
Correct Answer
Detailed Explanation
Using the given velocity and radius, the frequency of revolution is calculated as v / (2πr), yielding 6.6 × 10^15 Hz.
