  1. Question 1

    Q1. In the photoelectric effect, which factor determines the kinetic energy of ejected electrons?

    • A) Intensity of the incident light
    • B) Frequency of the incident light
    • C) Duration of light exposure
    • D) Work function of the metal

    Answer: Frequency of the incident light

    Explanation: Higher frequency light provides more energy per photon. Intensity affects electron number, not kinetic energy.
