Question

What is the speed of sound is it faster than light

Answer 1

no speed of sound is lesser than light

  the speed of sound is 340.29 m / s

Answer 2

Yes, light travels faster than sound. You can tell from several 
examples. The best would probably be that of lightning and thunder. The next 
time during a storm, if you notice when lightning flashes across the sky and 
when you hear thunder, you will find that it is always the lightning that 
flashes before the thunder. This is because lightning (i.e. light) travels 
faster than thunder (i.e. sound), and reaches you faster, so that you see the 
lightning before you hear the thunder. In fact, light is enormously faster than 
sound. Light travels at 300,000,000 metres per second (i.e. 300 million metres 
per second), while poor old sound travels only at 330 metres per second.
