  1. Question 1

    Q1. A wave has an amplitude of 2 cm and a frequency of 100 Hz. If its amplitude is doubled, what happens to its energy?

    • A) Remains the same
    • B) Doubles
    • C) Quadruples
    • D) Halves

    Answer: Quadruples

    Explanation: Energy is proportional to the square of the amplitude, so doubling amplitude quadruples energy. Option B is incorrect because energy does not just double.
