The speed of the wave in water is 833.33 m/s
The given parameters;
- depth of the wrecked ship, d = 1000 m
- frequency of the wave transmitted, f = 50 kHz
- time of motion of the echo, t = 2.4 s
The speed of the wave in water is calculated by applying echo equation as shown below;
Thus, the speed of the wave in water is 833.33 m/s
