Q)
(chatquestion)...A third harmonic standing wave (n = 3) is set up in a 3 m organ pipe that is open at the
non-driven end. The amplitude of the acoustic pressure is 0.5 percent of atmospheric
Problem 2:
pressure.
(A) Write expressions for y(x, t), ugp(x, t), Sp(x,
t) and Sp(x, t), where
y(x, t) displacement of the particle at
position x at time t.
Ugp(X, t) =
position x at time t.
õp(x, t) change in pressure at position x and at time t.
õp(x, t) = change in density at position x and at time t.
(B) Determine the values of amplitudes of the quantities in (A). (The temperature is 0°C.)
(C) What is the frequency of the standing wave?
