Problem

Three sound waves of the same frequency travel through the same medium. Their amplitudes are

2.0\,\text{mm}

4.0\,\text{mm}

, and

6.0\,\text{mm}

, respectively. (i) Rank the waves from greatest to least according to the energy they transport. (ii) If the wave with

6.0\,\text{mm}

amplitude transports

196\,\text{J}

of energy each second, calculate the energy transported per second by the other two waves.
