(c) Superposition.

(d) reflection and refraction.

To determine

The correct option for the statement “A sonic boom is the result of wave”.

Answer to Problem 10RAT

The correct option for the statement “A sonic boom is the result of wave” is option (a).

Explanation of Solution

When spherical waves overlap, the resultant conical waves results in shock waves. One of the main property of these conical waves is that they spread until it reaches the ground. The supersonic crafts are usually the source for these waves.

The sharp crack that the observer hears after a supersonic aircraft passed is due to the conical shell of air which is compressed that is the resultant of this supersonic aircraft movement and is described as a sonic boom. This is because compressional wavefront pile up and interfere to produce a very high-pressure zone. Instead of these compressional regions (high-pressure regions) reaching you one at a time in consecutive fashion, they all reach you at once.

Conclusion:

Therefore, correct option for the statement “A sonic boom is the result of wave” is option (a).
