Question

As we know, speed of light is much more than it is required for a sonic boom so, why doesn't it produce a sonic boom?

Answer 1

Sound requires a medium to propagate (example: air, water, solid) hence the energy produced in a speaker produces movement in the mass of the medium and therefore produces sound.Light having dual nature does not require a medium to travel in (it travels even in space which is a vacuum and no medium is present there) so it does not produce a sonic boom.

Answer 2

Answer:

But light, which always travels faster than sound does not produce a sonic boom. ... As the object move faster, these pressure waves gets forced together more and more and finally at the speed of sound, they combine to form a single shock wave.
