Sound needs gases to travel through, therefore it does not exist in a vacuum. In other words to my knowledge there is no experiments where sound is created in a vacuum.
-> Suspend an electric bell in an airtight bell jar attached to a vacuum pump. -> Turn on the electric bell. -> Pump out all the air in the bell jar using the vacuum pump. -> The sound of the bell should get fainter as air is pumped out. -> Finally no sound can be heard even though the hammer can be seen hitting the bell
One experiment is to use a bell inside a vacuum chamber. When the chamber is evacuated of air, the sound of the bell will not be heard because there is no medium (air) for the sound waves to travel through. This demonstrates that sound requires a medium to propagate.
Take a marinator with the hand vacuum pump 1. place your mobile phone inside seal it with the lid. now remove the air inside using the hand pump. Listen to the sound .. Gradually it will decrease.
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)
A vacuum does not make sound. Unlike a vacuum cleaner, which does!
The speed of sound cannot be measured in a vacuum because there is no medium for sound waves to travel through in a vacuum. Sound requires a medium such as air, water, or solids to propagate.
Space is a vacuum. Sound cannot travel in vacuum
The word notion has a long O and an unstressed schwa (shun, shen).
No. Sound is the vibration of air. Sound will not travel in a vacuum. Space is a vacuum
Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.
An experiment's results are considered reliable when they can be consistently reproduced in multiple trials by different researchers. Additionally, when the experiment's methodology is sound, and the results can be verified by peer review and further experimentation, the reliability of the findings is strengthened.
There is no sound in space or a vacuum.
