Unformatted text preview: calculate the intensity, intensity level, pressure amplitude, and displacement amplitude at distances of 5.0 m and 10.0 m from the speaker. Also calculate the ratio of the amplitude at 5 m to that at 10 m. 3. 1474. 4. Calculate the Fourier coefficients of the square wave of Fig. 1423. For coefficients that are zero, explain (by referring to the shape of the square wave) why they must be zero. Compare your results to Fig. 1424. 5. The phase velocity of deepwater waves is v ph = (gl/2p) 1/2 . Calculate the group velocity of a deepwater wave pulse with predominant wavelength l. Comment on the relationship between the two velocities. 6. 1435. 7. 1462....
