A message was transmitted from boat which returned to the sender after reflection from the bottom of the sea in 0.8 s. If the velocity of sound in water is `1500ms^-1` then find the depth of sea.

Ultrasonic signal sent from SONAR returns to it after reflection from a rock after a lapse of 1 sec. If the velocity of ultrasound in water is 1600 ms^(-1) , the depth of the rock in water is

If the same time taken for the reflected sound to reach the sonar os 2 s, the depth of the sea is _______ m. (velocity of sound in water is 1500 ms^(-1) )

A ship produces ultrasonic sound which is collected in 8 s after reflection from the surface of sea. If the velocity of ultrasonics is 1531ms^-1 , then what is the distance of sea surface from sea ?

An ultrasound signal of frequency 50 kHz is sent vertically into sea water. The signal gets reflected from the ocean bed and returns to the surface 0.80 s after it was emitted. The speed of sound in sea water is 1500ms^-1 . a. Find the depth of the sea. b. What is the wavelength of this signal in water.

If the depth of the sea is 1.125 km, the time taken for the reflected sound to reach the sonar is _________ s. (velocity of sound in water is 1500 ms^(-1) )
