What is the energy in joules of one photon of microwave radiation with a wavelength 0.122 m? (c = 2.9979 × 10 8 m/s; h = 6.626 × 10 –34 J×s)

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
