  1. Question 1

    Q1. The frequency of revolution of the electron in the nth orbit of hydrogen atom is given by f = me⁴ / (4ε0²n³h³). What is f for n = 2?

    • A) 6.54 * 10^15 Hz
    • B) 3.27 * 10^15 Hz
    • C) 8.2 * 10^14 Hz
    • D) 1.1 * 10^15 Hz

    Answer: 8.2 * 10^14 Hz

    Explanation: Substitute n = 2 in the given formula to get f = me⁴ / (4ε0²2³h³) = 8.2 * 10^14 Hz.
