The intensity of a sound wave at a fixed distance from a speaker vibrating at a frequency f' is 11. (a) determine the intensity if the frequency is increased to f' while a constant displacement amplitude is maintained. (use it, f for f', and fas necessary.) 12 = (b) calculate the intensity if the frequency is reduced to f/7 and the displacement amplitude is tripled. 12 = x 11
