Hey mate !!!
Hey mate !!!=>The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. ... This speed difference does become apparent, for example, with lightning.

This speed difference does become apparent, for example, with lightning.=>At supersonic speeds (those greater than the local sound speed), there is no sound heard as an object approaches an observer because the object is traveling faster than the sound it produces. Only after the object has passed will the observer be able to hear the sound waves emitted from the object.

Answer:
light speed is 299 792 458 m / s
sound speed is 344m/s
light need no medium to travel
sound need medium to travel
sound travels faster in solid ,medium in water ,slow in air
thank you
