    Q1. How does the photoelectric effect support the particle nature of light?

    • A) Light releases electrons in quantized packets
    • B) Light spreads as waves
    • C) Light requires medium to travel
    • D) Light intensity determines electron speed

    Answer: Light releases electrons in quantized packets

    Explanation: Photoelectric effect requires photons with threshold energy. Wave model fails here.
