  1. Question 1

    Q1. The frequency of revolution of the electron in the first Bohr orbit is

    • A) 6.58 * 10^15 Hz
    • B) 3.29 * 10^15 Hz
    • C) 1.65 * 10^16 Hz
    • D) 4.13 * 10^15 Hz

    Answer: 6.58 * 10^15 Hz

    Explanation: Using f = v / (2 * π * r), f = 2.2 * 10^6 / (2 * 3.14 * 0.53 * 10^-10) = 6.58 * 10^15 Hz.
