An ultrasonic wave is sent from a ship towards the bottom of the sea. It is found that the time interval between the sending and the receiving of the wave is . Calculate the depth of the sea, if the velocity of sound in sea water is .
Step 1: Given data:
Time interval
Velocity
Step 2: Formula used:
Where is the velocity, is the time interval, is the distance traveled by ultrasonic waves during
Step 3: Calculating the depth of the sea:
Let, the Depth of the sea is x,
Distance traveled by a sound wave
Time is taken by sound to travel both ways
Hence, the depth of the sea is
