The angle of the shock wave produced by a jet traveling at Mach 2 at an altitude of 3000 m assume the speed of sound to be 340 m/s at this altitude) is approximately A) 30^o. B) 40^o. C) 50^o. D) 60^o. E) 80^o.

Question

Quizplus · Accepted Answer

The angle of the shock wave, or Mach angle, is given by sin(θ) = 1/M, where M is the Mach number. For Mach 2, sin(θ) = 1/2, which gives θ ≈ 30°.
