L = V/F = 5.9*10^-4 m.
V/2.60 = 5.9*10^-4
V = 1.534*10^-3 m/uS.
d=1.534*10^-3m/uS * 11/2*!0^6uS=8440 m.
A sonar generator on a submarine produces periodic ultrasonic waves at a frequency of 2.60MHz . The wavelength of the waves in seawater is 5.90×10−4m . When the generator is directed downward, an echo reflected from the ocean floor is received 11.0s later.
Part A
How deep is the ocean at that point?
