What happens if light and sound travels at same speed?

I think the best place to start answering What would happen if the speed of sound were similar to the speed of light? in a meaningful way would be to first try to understand how sound travels, the mechanics of it. read more

A 680-Hz sound wave travels at 340 m/s in air, with a wavelength of .5 m Beats are produced when two tuning forks, one of frequency 240 Hz and the other of frequency 249 Hz, are sounded together. read more

No, since light is an electromagnetic wave it travels at a speed of 3 X 10^8 m/s. The sound is basically a propagation of vibration through material in the medium. So the speed of sound depends on a lot of factors like density of the medium, the elasticity of the medium etc. read more

Light doesn't need a medium to pass through, but it can pass through media, and it's"average" speed, or group velocity, decreases compared to a vacuum; there are some materials which are stiff enough that the speed of sound exceeds the speed of light (within that medium). read more
