Does sound travel faster in water or air?
Sound travels faster in water compared with air because water particles are packed in more densely.
Thus, the energy the sound waves carry is transported faster..
What is difference between echo and reflection of sound?
An echo is a single reflection of a soundwave off a distance surface. Reverberation is the reflection of sound waves created by the superposition of such echoes. An echo can only be heard by humans when the distance between the source of the sound and the reflecting body is more than 50 feet in distance.
Can sound waves travel in a vacuum?
IN SPACE, no one can hear you scream. Sound waves are travelling vibrations of particles in media such as air, water or metal. … So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
How fast does sound travel in space?
Thus, Cs is a legitimate type of sound speed in space. In the IPM, Cs ~ 13 – 240 km/s [e.g., Refs.
Do sound waves go on forever?
Sound waves do not live forever. … As the energy of the sound is transferred to more and more molecules of air, they vibrate less and less until the effect is lost in the constant random jostle of air molecules.
Why can sound not travel in space?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.
What can sound not travel through?
Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.
Will a body decay in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.
Why is Echo weaker than the original sound?
Answer and Explanation: An echo is weaker than the original sound because it’s produced by a sound wave which travels through the air and then hits another surface, after…
What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.
How is sound transferred?
Sound is transmitted through the air as sound waves from the environment. The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. … These electrical impulses are transmitted to the hearing (auditory) nerve and up to the brain, where they are interpreted as sound.
Can you smell a fart in space?
In space, no one can hear you fart (but they can smell it). They can! Zero gravity could even help them to travel, if the aroma was spreading through a virtual vacuum. Smells travel by the movement of individual aroma molecules.
Can light travel forever?
If there were no objects to absorb light, it would keep traveling forever. Light is made up of particles called photons that travel like waves. Unless they interact with other particles (objects), there is nothing to stop them. … If it is infinite, the light would travel forever.
How much more intense is a close whisper than a sound at the threshold of hearing?
A close whisper is 100 times more intense than the threshold of breathing. A close whisper is 10 times more intense that normal breathing.
