2) A wave moves from medium n₁ to medium №2. a) Write the expressions for the coefficients of transmission and reflection for the case of normal incidence using that μ can be approximated as μo for both mediums. b) Using the results from the previous part, find the intensity of the incident and reflected wave in terms of n₁, n₂ and the intensity of the transmitted wave IT. c) Check that if n₁ n2, we get that IR = 0 and I₁ = IT.

(a) If a submarine’s sonar can measure echo times with a precision of 0.0100 s, what is the smallest difference in distances it can detect? (Assume that the submarine is in the ocean, not in fresh water.) (b) Discuss the limits this time resolution imposes on the ability of the sonar system to detect the size and shape of the object creating the echo.
(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.)
