A submarine emits a sonar pulse, which returns from underwater cliff in 2.02 s. If the speed of sound in salt water is `1531ms^-1` how far away is the cliff ?

A submarine emits a sonar pilse, which returns from an underwater cliff in 1.02 s . If the speed of sound in water is 1531 m//s , how far away is the cliff ?

A ship sends out ultrasound that returns form the seabed and is detected after 3.42 s . If the speed of the ultrasound through sea water is 1531 m//s , what is the distance of the seabed from the ship ?

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.

Read the given passage and select the correct option for the following questions. The sound returning back towards the source after suffering reflection from a distant obstacle like wall, hill etc. is called an echo. A cracker is fired by a child. The child hears an echo from a cliff 4 seconds after the sound produced by a cracker. The speed of sound in air at 20^(@)C is 344 ms^(-1) . How far is the cliff from the child?

Sound signal of frequency 40 kHz is sent vertically into sea water. The signal gets reflected from the ocean bed and returns to the surface 0.60 s after it was emitted. The speed of sound in sea water is 1500 ms^(-1) . What is the depth of the sea and wavelength of this signal in water.

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.

A thunder is heard 2 s after a flash a flash of lightning is seen. If the velocity of sound in air is 330 ms^(-1) , how far away from you has lightning occurred ?

An ultrasonic transducer used in sonar produces a frequency of 40 kHz. If the velocity of the sound wave in seawater is 5050 ft/s, what is the wavelength ? The transducer is made to emit a short burst ofsound and is then turned off. The receiver is turned on. The pulse is reflected from a lurking submarine and received 5.0 s after it was first emitted. How far away is the submarine ?
