Sound requires a medium to travel. It is basically a tranfer of energy from one particle to another and hence faces a lot of resistance whereas light does not require a medium to travel it can travel through vacuum,it is an electromagnetic wave.No information can travel faster than light.The speed of sound is 340m/s on the other hand the velocity of light is 3 cross times 10 to the power of 8 m divided by s
