Assertion (A): Shock diamonds form in the exhaust of a rocket whose nozzle is not perfectly expanded.
Reason (R): Waves reflecting from the constant-pressure plume boundary return with their sense reversed.
Select the correct answer from the options below.
Answer: B
Both statements are true and the second is the reason for the first. An expansion reflects from the free boundary as a compression and vice versa, so the plume oscillates between under- and over-pressure, producing the periodic bright regions. Viscous mixing eventually damps the pattern out.
