Question

A wave is made by moving a rope up and down. If the amplitude of the wave is doubled, the energy carried by the wave will be
times greater.

The energy carried by a wave is proportional to the square of its amplitude. This means that if the amplitude of the wave is doubled, the energy will increase by a factor of \(2^2 = 4\). Therefore, if the amplitude is doubled, the energy carried by the wave will be **4 times greater**.
