they probably would use a sonar which is a device that bounces sound waves off under water objects and then records the echoes of these sound waves. =]
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
Yes, echoes can occur underwater. When a sound wave hits an object, such as the seabed or a submerged object, the sound wave bounces off and returns to the source, creating an echo. The depth and composition of the water, as well as the frequency of the sound wave, can affect the strength and clarity of the echo.
It bounces back; echoes.
cause the sound bounces off other mountains and you hear the echoes.
Sonar uses echoes to locate objects by bouncing sound waves off them and detecting the echoes.
sonar - by bouncing sound signals off the bottom of the ocean, they were able to map the depth of the ocean. Deep sea diving would take too long. Satellites were not in orbit until the 1970's and submarines were not necessary since sonar could be done from the surface on a boat.
Sonar
It echoes and then bounces around the room. (Like sound does) As it is a echoey building.
An echo is a reflection of sound that may come from many places. Examples of echoes could be when sound bounces off the bottom of a well or a large room. There is a delay depending on distance.
it measures the depth under water
Yes, echoes are important because they can provide information about the surroundings, such as the size and distance of objects. In nature, echoes are used by animals for navigation and communication. In technology, echoes are utilized in echo-location systems like sonar and radar for a variety of applications.
