Which statement about a detached bow shock is FALSE?

  • A.It forms when the required deflection exceeds the maximum
  • B.It lies closer to the body as the free-stream Mach number falls
  • C.It is effectively normal at the stagnation streamline
  • D.It weakens with distance away from the body

Answer: B

The shock stands further off as the Mach number falls, not closer; at hypersonic speeds it wraps in tight against the body and produces the characteristically thin shock layer. The other three statements correctly describe a bow shock.
