A sonar generator on a ship produces a sound wave with a frequency of 2.45 MHz and a wavelength of 5.9 * 10^-4 m.The generator is pointed straight down and emits a pulse.The echo of this pulse is received 5.08 s later.How deep is the ocean at this point? A)34.5 m B)121 m C)3670 m D)8810 m E)51,200 m

The speed of sound in sea water is around 1530 m/s.

Using the formula v = λf, we can find the speed of the sound wave generated by the sonar:

v = (5.9 x 10^-4) x (2.45 x 10^6) = 1445.5 m/s

Next, we can use the formula d = (v/2) x t to find the depth of the ocean:

d = (1445.5/2) x 5.08 = 3672.5 m ≈ 3670 m

Therefore, the best answer is C, 3670 m.
