The frequency of revolution of an electron in the nth orbit is given by f = v / (2πr). For n = 2, what is f?
Q1. The frequency of revolution of an electron in the nth orbit is given by f = v / (2πr). For n = 2, what is f?
Answer: 1.65 * 10¹⁵ Hz
Explanation: Using f = v / (2πr) and v = v1 / n, r = n²r1, f = (v1 / n) / (2πn²r1) = v1 / (2πn³r1). For n = 2, f = 1.65 * 10¹⁵ Hz (approximate values used).
