16.11 Exercise 11

Avg difficulty 2.5

A microphone receiving a pure sound tone feeds an oscilloscope, producing a wave on its screen. If the sound intensity is originally 2.00 × 10 –5 W/m 2 , \text{2}.\text{00 } \times \text{10}^{–\text{5}} \text{W}/\text{m }^{2} , but is turned up until the amplitude increases by 30.0%, what is the new intensity?
