  1. Question 1

    Q1. What is the frequency of the photon emitted when an electron jumps from n = 3 to n = 1 in a hydrogen atom?

    • A) 2.92 x 10^15 Hz
    • B) 1.46 x 10^15 Hz
    • C) 2.46 x 10^15 Hz
    • D) 3.46 x 10^15 Hz

    Answer: 2.92 x 10^15 Hz

    Explanation: Using energy difference between n = 3 and n = 1, and E = hf, frequency is calculated as 2.92 x 10^15 Hz.
