How does a sonar works in a boat or a ship?
Sonar is the technique of listening to sounds underwater to detrmine what is there. In passive sonar, objects not generating any sound will not be detected. Active sonar means that sound waves are generated and emitted. The device then listens for the sound being reflected back. That detects objects such as obstructions/rocks as well as other boats or underwater objects. The reflected wave is measured and the time delay noted as well as the direction of the reflected sound wave. These give the user a very good idea of the type, size as well as speed of the object.
What type of radiation does the universe emit the most?
Radio waves they are low frequencey; and it is what is emitted at very low temperatures
What type of radiation is emitted by molybdenum-99?
???
Which type of electromagnetic wave is used in photography?
The same ones used in the camera for taking the pictures, usually the visible light spectrum waves. Some older autofocusing systems (e.g. one used on some Polaroid instant cameras) used a SONAR ranging system, which used sound waves not electromagnetic waves.
What is a type of wave that is emitted by all warm bodies?
heat
What are some technological applications of sound waves?
Sonar (or Sound Navigation and Ranging) is a type of technology that was designed to help with navigation, communication and locate objects underwater. Sonar projects sound waves then listens for the echo of the emitted sound waves to detect objects.

How can you be detected under water when scuba-diving?
Diver can be detected by the air bubble they give off if NOT using a closed circuit rebrether. Additionally they can be detected with sonar as well as a hand held depth sonar type detector but at a limited range.
Which type of electromagnetic wave will be emitted by a cooler object?
The type of electromagnetic waves that will be emitted by a cooler object are waves with long wavelengths. The wavelength of peak emission is determined by Wien's Law.
What type of electromagnetic energy is detected by bats?
Bats can detect bio-sonar. They use it for echolocation.
What type of electromagnetic radiation is detected by an optical telescope?
Radio Waves
What type of wavefront will emerge from a point source and distant light source?
For a point in space (or from a distant light object), spherical waves are emitted. From a point source on the surface of a liquid, circular waves will come out. In both cases the source will be the focus of the emitted waves.
Form of sonar used to detect and locate enemy submarines by means of ultrasonic waves?
Type your answer here... ASDIC
Which type of invisible radiation can be detected from earths surface?
Radio waves are one example.
Which kinds of sound waves can be produced by bats?
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
What type of radiation does the universe emit the most?
Radio waves they are low frequencey; and it is what is emitted at very low temperatures
Which type of seismic waves cannot be detected on the side of Earth opposite an earthquake?
The type of wave that cannot be detected on the other side of Earth is a secondary wave also known as a s wave
