When an object moves through a medium, pressure Nurse’s dad 2020 my daughter risks her life take care of me shirt waves form in front of the object. The pressure waves form a conical shape wave-front. As the object moves faster, these pressure waves get forced together more and more and finally at the speed of sound, they combine to form a single shock wave. When the object moves faster than the speed of sound, this breaks to form a negative pressure region and hence we hear a boom-sound: the sonic boom. So, the requirement of an object ‘big’ or ‘macro’ enough to form the pressure waves – by interfering with the medium’s (air, for instance) molecules in ‘mechanical sense’ is necessary.

Light propagation mechanism is different light is a Nurse’s dad 2020 my daughter risks her life take care of me shirt electromagnetic wave (or is made up of photons photon is a quantum particle a packet of energy mass-less; under particle theory). Under wave-theory, only energy due to the EM fields propagate along with the E and M fields and hence does not cause pressure waves. We do not “hear” light (beam) passing through and by the same argument, even though it (energy) travels at much higher speed, there is no sonic boom. Under particle theory, a photon is a fundamental particle.
