What is the word supersonic word means?
When the speed of a thing is greater to that of sound present in the air (generally one to five times more) then it is denoted as "supersonic." In Physics it is related to sound waves that are beyond the capacity of human hearing. By the year 1934, it was started using as the movement which exceeds the speed of sound.
Anything supersonic is quick to such an extent that you see it before you hear it. A fast-moving airplane is supersonic, however, there aren't any supersonic passenger airplanes since Concorde's retirement in 2003. A great example to understand the term in our daily life is the bomber plane which bombs on the target so fast that the target is still over the horizon.
