Question

In an organ pipe whose one end is at x = 0, the pressure is expressed by p = p0cos $\frac{3\pi x}{2}$sin 300πt where x is in meter and t in sec. The organ pipe can be

Accepted Answer

Sol. K = $\frac{2\pi}{\lambda}$ = $\frac{3\pi}{2}$⇒ λ = $\frac{4}{3}m$For pipe closed at both endsL = $n\frac{\lambda}{2}$(C) 2 = $n 	imes \frac{2}{3}$ ⇒ n = 3For pipe closed at one end⇒ L = $\left( n + \frac{1}{2} ight)\frac{\lambda}{2}$ No option satisfies for integral value of n
