What Is A Sonic Boom?

hi I'm emerald Robinson and in this a

what is a video we're going to answer

the question what is a sonic boom a

sonic boom is the noise produced by

something moving through the air faster

than the speed of sound but how is a

sonic boom produced as an object moves

through the air it forces air molecules

out of its way creating waves these

waves move away from the object or

propagate if the object moves faster

than these waves can propagate the waves

become more and more compressed

eventually they're unable to get out of

the way of the moving object quickly

enough and combine into one large shock

wave that trails behind the object sonic

booms come from the shock wave created

by an object moving faster than its own

sound waves the shock wave forms a cone

shape around the object with the tip of

the cone at the front and the base

trailing behind when you first see the

object appears to be moving without

making any noise it's only when the base

of the cone reaches your ears that you

hear the boom in order to create a sonic

boom an object must move faster than a

speed of sound

about 700 miles per hour sometimes

physicists call this speed Mach 1

anything moving faster than Mach 1 is

moving faster than the speed of sound

any object that moves faster than Mach 1

makes a sonic boom

although we usually associate airplanes

and spacecraft with sonic booms meteors

and other objects entering the Earth's

atmosphere from space making them to a

whips crack is a mini sonic boom created

when its tip moves faster than the speed

of sound

even nature makes sonic booms lightning

makes air molecules move faster than the

speed of sound and causes the sonic boom

we call thunder for thousands of how-to
