The “ears” of a frog are two circular membranes locatedbehindthe frog’s eyes. In one species of frog each membrane is 0.500 cmin radius. If a source of sound has a power output of 2.50 * 10-6 W,emits sound equally in all directions, and is located 1.50 m from thefrog, how much sound energy arrives at one of the membranes eachsecond?
Find the range of wavelengths emitted by the bat in meters, by using that the speed of sound is c=343m/sec and the range of frequencies from 70 to 30KHz. The solution matches the range of sizes for an insect. What is the order of magnitude for this range? Take this order and call it L for the average size of an insect.
b) If the bat produces a power of P = 10^-5 watts and its hearing threshold is 10^-12 watts/m^2 what is the maximum distance from which the bat can detect an echo?
When one face of a slab of rock is struck with a hammer, a detector at the opposite face of the
slab 0.85 m away records seismic waves at 230 µs and 425 µs. Calculate the Vp and Vs. If the
density of the rock is 2.6 g/cm³, what are the bulk and shear moduli for the rock?
