In general, sound waves are longitudinal waves that need medium to move through, its speed varies from 300m/s to 346m/s. While visualizing the scene depends on the speed of light which is an electromagnetic waves that need no medium to move through and which have a speed of [tex]3*10^8m/s[/tex].
Light waves compared to sound waves have higher speed, higher energy, higher frequency, shorter wave length.
In general; the shorter the wave length, the higher the energy, the higher the speed, the higher the frequency.
Hope this helps.
