Problem 2 (HRK). Some conceptual questions about sound waves.
(a) What is larger for a sound wave, the relative density variations ∆ρ/ρ or the relative pressure
variations ∆P/P? Or does it depend on the situation?
(b) What is larger, the velocity of a sound wave v or the amplitude of the velocity variations ∆u
of the underlying particles? Or does it depend on the situation?
