Write your answers on a separate sheet of paper. 1. When dolphin swims close to its prey, it transmits sound waves to figure out details (like direction where the fish is moving) of its prey. Now, if the frequency of the reflected waves has increased, would the dolphin catch up its prey or fall behind? Explain your answer.

(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)
