When a sound moves from one density to another it loses a lot of energy. That is why you can't hear sound very well through doors. You may be interested to know that sound travels faster in water than air because water is more dense.
Things vibrating, such as a speaker or your voice box.
Because you've never listened? I have, and I find it quite easy to hear sound travelling through water.
Mach is the speed of an object expressed as a multiple of the speed of sound in the same medium. Thus, an object travelling at 686 metres per second through air, at sea level, is travelling at Mach 2 because sound would travel through it at 343 m/s. However, it the object was travelling under water at the same speed then it would be travelling at approx Mach 0.46 since sound travels at 1484 m/s through water.
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
No, an octopus cannot survive outside of water because they require water to breathe and move.
Sound is a type of wave that is created by vibrations travelling through a medium, such as air, water, or solids. Sound waves carry energy that our ears can detect and perceive as sound.
Sonar technology relies on sound waves traveling through a medium, such as water, to detect objects. Sonar cannot be effectively used out of water because air does not transmit sound waves in the same way as water does, resulting in distorted or ineffective results.
Air and water are sound transfer mediums. Unless acted upon by an outside force, neither air nor water makes sound.
No, octopuses cannot survive outside of water for an extended period of time as they require water to breathe and move.
No, sound cannot travel through the vacuum of space because it requires a medium, such as air or water, to propagate. Astronauts can hear inside their spacecrafts where there is air, but they cannot hear anything outside in the vacuum of space.
Sound cannot travel through a vacuum because it requires a medium, such as air or water, to transmit vibrations. In a vacuum, there are no particles for the sound waves to travel through, so the sound cannot propagate.
