  1. Question 1

    Q1. How does the photoelectric effect contradict classical wave theory predictions?

    • A) Electron emission occurs only above a threshold frequency.
    • B) Light intensity affects emission rate.
    • C) Energy transfer depends on wavelength.
    • D) Photoelectrons show discrete energy levels.

    Answer: Electron emission occurs only above a threshold frequency.

    Explanation: Threshold frequency supports photon particle nature. Option B aligns with classical wave theory, not a contradiction.
