Does sound travel better 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 was the loudest sound on earth?
KrakatoaKrakatoa is believed to be the loudest sound produced on the surface of the planet — in human history, that is. It circled the Earth four times in every direction and shattered the ears of sailors 40 miles away. The Krakatoa volcano erupted with ungodly strength, sending ripples of sound heard thousands of miles away.
How long do sound waves travel?
Sound waves can travel through any material, but not in a vacuum, which is why there is no sound in outer space. The speed of sound in air is about 330 m/s, meaning that it covers a mile in about five seconds.
Are Sound Waves infinite?
The answer is no. As waves travel through a medium, they spread out and the energy in them spreads out as well. … One way we have of getting sound waves to carry information over long distances is to change them to electromagnetic waves which travel at the speed of light: MUCH faster than sound.
What can sound not travel through?
vacuumSound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
Can whales kill you with sound?
Sperm Whales Are So Loud They Could Potentially “Vibrate” You to Death. Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels.
Is anything faster than light?
Nothing can move faster than the speed of light. When Einstein set forth his theory of relativity, this was his inviolable postulate: that there was an ultimate cosmic speed limit, and that only massless particles could ever attain it. All massive particles could only approach it, but would never reach it.
What frequency can kill you?
The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
Can light be destroyed?
Light is a form of energy. Energy can neither be created, nor destroyed. It can only be changed from one form to another form. … It is form of energy which can be transformed in another form but cannot be destroyed..
Does light have a distance limit?
Light is able to travel infinite distance, unless it is blocked by some obstacle. This is because according to the special theory of relativity, time doesn’t flow for anything that travels with the speed of light, and the only thing in the universe which can achieve this much speed is light itself.
Can sound travel underwater?
The sound waves don’t move through the air, they move through the water. Sound waves actually travel five times faster in water than in air. Underwater those sound waves don’t vibrate the ossicles bones in your inner ear. … Air is so different from flesh that the sound waves are able to vibrate off your fleshy bits.
Do sound waves exist forever?
Originally Answered: Does every sound we utter remain in the universe as sound waves for ever ? No. First the wave expands and thereby weakens. Then, if it impacts something, the energy is absorbed and changed to heat.
Does light go on forever?
Light is made up of particles called photons that travel like waves. … Unlike some types of particles, they do not decay, meaning that they do not spontaneously turn into other types of particles. With nothing to stop them and no chance of decaying, the will keep going forever.
Why is sound not heard 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. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
Do sounds ever die?
To create a sound, we have to set matter – whether it’s a gas like air, a liquid or even a solid material – in regular motion, creating a wave of specific frequencies, which we hear as a sound of a particular pitch. … Eventually the motion ceases entirely and no more sound can be heard – producing silence.
Can you hear someone talk in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
Can a sonic boom kill you?
The boom is not deadly but it can cause some severe damage to the body and hearing if you happen to be at the exact spot of the boom. The boom can and has caused a lot if damage to homes in the past, thus the restriction for such flights over populated areas.
