Do sound waves travel faster in light than in the darkness? I was wondering if they could "ride" lightwaves...

Question

Can soundwaves travel with lightwaves and go further faster than in the dark?

Answer 1

Sorry, but sound travels faster in darkness. Air is more dense at night than it is during the day.

Answer 2

Light waves and sound waves are not physically similar, that's like comparing apples to rocks. Sound waves can't ride light waves and the presence of light doesn't speed up sound. However, the speed of sound can be affected by temperature, so in general, sound will travel faster during the day than at night simply because of the difference in temperature (the light is just incidental). Here is a link where you can plug in an air temperature and see how it will affect the speed of sound.

Addendum: Ok, I really hate to get off topic here, but Helmut seems to have some of his facts mixed up. To quote Wikipedia (which I hate doing but it has the best quote for my purposes):

"The speed (of sound) varies depending on atmospheric conditions; the most important factor is the temperature. Air pressure has almost no effect on sound speed. Air pressure has no effect at all in an ideal gas approximation, because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature."

Answer 3

Sound strikes approximately 1500 meters according to 2nd in seawater. this is approximately 15 soccer fields end-to-bring about one 2nd. Sound strikes lots greater slowly in air, at approximately 340 meters according to 2nd, purely 3 soccer fields a 2nd the linked fee that gentle travels, 3 hundred,000 km/s, is the quickest that something has been measured to pass in the universe. this is an rather severe velocity(670 million miles according to hour), yet no longer countless. So gentle -- and in certainty no longer something -- can return and forth from one element to a various straight away.

Answer 4

Light and dark makes no difference - because sound is the result of molecules, not light, impacting one another like millions of tiny dominos vibrating back and forth. But sound CAN travel on light. Turn on your nearest radio for a quick example.

Answer 5

Darkness technically doesn't exist, it is just a term used to describe the absence of visual light. Therefore, the speed of light and the speed of sound, would remain constant, through the same mediums( air, water, etc.)
Sound waves dissipate more quickly than light, because of their length.

Answer 6

Nope, they travel at the same speed...No difference between one dark medium and one illuminated one....its just an illusion...
They can not "ride " light wavelenghts, because the sound waves are coarse, and measured in meters (both amplitude and frequency), and light waves are so tiny.....(sometimes we dont know wheter they are waves, particles (photons ) or a mixture of both,,,,,so no...its impossible,...no riding sound on light waves.....(It would be a Nobel winning Prize to make it a reality)-------
