Question

what is a sonic boom ​

Answer 1

$\Large{\underline{\underline{\bf{Solition :}}}}$

When a body moves with a speed which is greater than the speed of sound in air, it is said to be travelling at supersonic speed jet fighters, bullets, etc, often travel at supersonic speed, and when they do so, they produce a sharp, loud sound called a sonic boom.

The source moves at a speed greater than that of sound, sound waves travelling at the speed of sound, are left behind. The high-pressure layers due to sound waves originating at different points bunch together as shown in figure. Actually, these layers fall on the surface of an imaginary cone of which OA, OB is a part. The total pressure on the surface of this cone is very high. The source is at the apex of this cone. As the source moves ahead, it drags the cone together with it. when the surface of the cone reaches a person, the ears experience a sudden increase in pressure. After the surface crosses him, the pressure is suddenly reduced. This causes the person to hear a sharp, loud sound-the sonic boom.

A region consisting of a very-high-pressure layer followed by a lower-pressure layer travels through the space together with the cone. This is called a shock wave. This shock wave gives rise to the sonic boom when it reaches a person.

The shock waves produced by supersonic aircraft have enough energy to shatter glass and even damage weak structure.

Answer 2

$\huge{\underline{\underline{\mathfrak{Answer:-}}}}$

Sonic boom can be defined as a loud voice generated when any object travels in sky (air) faster than the speed of Sound.

• It often sound like an explosion.

• Sometimes it generates shock too.

• It may cause damage in some structurrs.

• It is caused by the shock waves.

There are 2 types of wave generated in Sonic Boom-

• N-waves.

• U-waves.

$\huge{\underline{\mathfrak{Additional\: Information-}}}$

• Sonic Boom can approach 100 megawatts per square meter.

• It may exceeds to 200 decibels.

• Speed of sonic boom is 750 miles per hour.

• F-4 flying jet produce the boom.

$\huge{\underline{\mathfrak{Attachment-}}}$

• 1st attachment is of Sonic Boom.

• 2nd attachment is of U wave.

• 3rd one attachment is of V wave.
