  1. Question 1

    Q1. The frequency of the radiation emitted when an electron jumps from n = 3 to n = 2 is

    • A) 4.57 x 10¹⁴ Hz
    • B) 3.29 x 10¹⁵ Hz
    • C) 4.57 x 10¹⁵ Hz
    • D) 3.29 x 10¹⁴ Hz

    Answer: 4.57 x 10¹⁴ Hz

    Explanation: Using the Rydberg formula and the energy difference between n = 3 and n = 2, the frequency can be calculated.
