Question

Q4/ A sound wave penetrated two layers of the earth's surface and the total time of the
wave reflected from the second barrier equals 2 seconds. If you know that the wave's speed in the
medium is 200 m/s and in the second medium is 300 m/s, what is the depth of the second medium
if the depth of the first is m 100?

3. Two loudspeakers emit sound waves along the r-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at r = 0.50 m. If speaker 1 is slowly moved forward, the sound intensity decrcases and then increases, reaching another maximum when speaker 1 is at x = 0.90 m. a. What is the frequency of the sound? Assume vsound = 340 m/s. b. What is the phase difference between the spcakers?

X/10. It is √gd, so A water wave is a shallow-water wave if the water depth d is less than shown in hydrodynamics that the speed of a shallow-water wave is v = waves slow down as they move into shallower water. Ocean waves, with wavelengths of typically 100 m, are shallow-water waves when the water depth is less than 10 m. Consider a beach where the depth increases linearly with distance from the shore until reaching a depth of 5.4 m at a distance of 100 m. Part A How long does it take a wave to move the last 100 m to the shore? Assume that the waves are so small that they don't break before reaching the shore.
