NEET Physics Bohr Model MCQ Question
What is the calculated initial frequency of light emitted by an electron in a hydrogen atom orbiting at a radius of 5.3 × 10^-11 m, given its velocity is 2.2 × 10^6 m/s?
6.6 × 10^15 Hz
4 × 10^15 Hz
3 × 10^15 Hz
8.8 × 10^15 Hz
Correct Answer
Detailed Explanation
The frequency is calculated using ν = v / (2πr), where v = 2.2 × 10^6 m/s and r = 5.3 × 10^-11 m. This gives ν ≈ 6.6 × 10^15 Hz.
