It is told that sound cannot travel trough vacuum. Sound can only travel through medium.

Is the velocity of sound at its maximum in a vacuum?

No, sound cannot travel through a vacuum because it requires a medium, such as air or water, to propagate. In an environment with no medium, like a vacuum, sound waves cannot travel and therefore do not have a velocity.


Speed of light is minimum in?

the velocity of light is maximum in vacuum I.e 3*10^8 m/s. as the density of the medium increases the velocity of light decreases in the medium. so the velocity of light is less in watt than in atmosphere. the thicker the medium is the slower the electromagnetic wave, so the velocity of light will be minimum in the thickest medium.


Where is Velocity of sound the most- in air or water or vacuum or in iron?

Sound is a mechanical wave, so it can't travel in vacuum. Sound speed will be higher when the molecules of the material it is traveling are closer to each other, this means that it travels the fastest in solids, medium speed in liquids and slower in gases. In vacuum, the speed of sound is zero. Sound doesn't propagate through vacuum. Shout as loud as you want to, and the sound goes nowhere if there's no medium to carry it. Two astronauts standing next to each other on the surface of the moon can communicate only by radio, or by touching their helmets together.


Why there is no sound year like light year?

The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.


How does the speed of sound change in a vacuum?

sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)


In which materials is the velocity of light greatest?

A vacuum, so no material


Velocity of light greatest?

in a vacuum


When was Velocity of Sound created?

Velocity of Sound was created on 2002-10-08.


What does not make sound?

A vacuum does not make sound. Unlike a vacuum cleaner, which does!


What is the velocity of sound in space?

Sound requires the physical compression and expansion of molecules to be transmitted, it is not electromagnetic energy like light and microwaves. It therefore cannot be transmitted through a vacuum so it cannot have a velocity in space


What is the approximate velocity of the sound in air?

the velocity of sound in the air is 300m/s


Can sound travle to space?

Space is a vacuum. Sound cannot travel in vacuum
