Does the conical angle of a shock wave open wider, narrow down, or remain constant as a supersonic aircraft increases its speed?
To determine:
Whether the conical angle of a shock wave open wider, narrow down, or remain constant when supersonic aircraft increases its speed.
Answer:
The conical angle of a shock wave will be narrow down.
Explanation:
When the speed of a source surpasses the speed of sound
Write the expression for the mach angle at the vertex of the shock cone.
Here,
c is the speed of light
v is the speed of object
Now, when the speed of supersonic aircraft increases, the mach angle got reduced. Therefore, the conical angle of a shock wave will be narrow down.
Conclusion:
Therefore, the conical angle of a shock wave will be narrow down.
