Unformatted text preview: = × =--β I r P c) With the result of part (a), the amplitudes, either displacement or pressure, must be subtracted. That is, the intensity is found by taking the square roots of the intensities found in part (b), subtracting, and squaring the difference. The result is that dB. 62.1 and W 10 60 . 1 6 = × =-β I...
