Question
In an organ pipe whose one end is at x = 0, the pressure is expressed by P = P0 cos 
sin 300πt where x is in meter and t in sec. The organ pipe can be : -
sin 300πt where x is in meter and t in sec. The organ pipe can be : -Options
A.Closed at one end, open at another with length = 0.5 m
B.Open at both ends, length = 1m
C.Closed at both ends, length = 2m
D.Closed at one end, open at another with length = 2/3 m
Solution
⇒ = 
Pr. Amp. = p0 cos 
= P0 at x = 0and - P0 at x = 2/3 = P0 at x = 4/3
∴ Pipe may be closed at x = 0 and open at x =
