Question

A ship sends a 1200 Hz sound wave down in the water, and detect the echo 3 seconds later what would happen if that ship sent out a 600 Hz sound wave instead? A) The sound would travel half as fast, so it would take twice as much time to return

B) The sound would travel half as fast, so it would take half as much time to return
C) the sound would travel twice as fast, so it would take half as much time to return
D) The sound would travel the same speed, so it would take the same amount to time to return
E) The sound would travel the same speed, so it would take half as much time to return
F) The sound would travel twice as fast, so it would take twice as much time to return

Answer 1

D) The sound would travel the same speed, so it would take the same amount to time to return

Step-by-step explanation:

The speed of sound in water is constant, decreasing the frequency will only serve to increase the wavelenght of the sound wave, it doesn't affect the speed of the Sound wave.

Speed of sound = Freq. X wavelenght
