A sound pulse emitted underwater reflects off a school of fish and is detected at the same place 0.01 seconds later. How far away are the fish?

Asked by Marsaw293

Answer (3)

In fresh water sound waves travel at 1497m/s at 25 degrees, I'll assume that's the characteristics of the water.
If it's 0.01s then you need to divide the speed by 100 to get the, 14.97, however it gets there and back in that time so you need to halve it. 7.485m

The fish are approximately 15 meters away from the place where the sound pulse was emitted. ;

The school of fish is approximately 7.5 meters away from the point where the sound pulse was emitted. This is calculated using the speed of sound in water and the time it took for the pulse to travel to the fish and back. By dividing the total time by two and applying the distance formula, we find the distance to the fish.
