    The energy becomes 4 times greater.

    Explanation:

    We know that the energy of a wave is proportional to the square of its amplitude

    E ∝ Amplitude^2

    Since the original amplitude = 0.5 m

    and the new amplitude becomes = 1 m

    We are doubling the amplitude. This means that the new energy will be affected by a factor of 4

    E_new ∝ (2*Amplitude) ^2 =

    E_new ∝ 4 * (Amplitude) ^2

    E_new = 4*E
