Ultrasonic waves are transmitted downwards into the sea with the help of a SONAR. The reflected sound is received after 4 s. What is the depth of the sea at that place?
(Velocity of sound in seawater =`1550 m//s`)

Text Solution

Verified by Experts

Velocity of sound in seawater = 1550 m/s
Time for echo to be heard = 4s
Time taken by sound waves to reach the
bottom of the sea `= (4)/(2) = 2 s `
` " Velocity " = (" Distance ")/(" Time ") `
Distance = Velocity ` xx ` Time
` = 1550 xx 2 = 3100 m `
Depth of the sea at that place = 3100 m
