Physics-Bohr Model
NEET Physics Bohr Model MCQ Question
Type: MCQ-numerical-Easy-Class 12
In the Bohr model of the hydrogen atom, what is the frequency of the electromagnetic waves emitted when the electron orbits a proton at a radius of 5.3 × 10⁻¹¹ m with a speed of 2.2 × 10⁶ m/s?
A
6.6 × 10¹⁵ Hz
B
3.3 × 10¹⁵ Hz
C
1.1 × 10¹⁵ Hz
D
2.2 × 10¹⁵ Hz
Correct Answer
Option A
Detailed Explanation
The frequency of the electromagnetic waves emitted is equal to the frequency of the electron's revolution, calculated as v/2πr = 6.6 × 10¹⁵ Hz using given values.
