An ultrasonic wave is sent from a ship towards the bottom of the sea. It is found that the time interval between the transmission and reception of the wave is \(1.6\) seconds. What is the depth of the sea, if the velocity of sound in the seawater is \(1400\) \(m/s\)?
 
The depth of the sea can be found using the formula,
 
 
The depth of the sea is  \(m\)
