An air column in a pipe, which is closed at one end will be in resonance with a vibrating tuning fork of frequency 264 ~Hz for various lengths. Which one of the following lengths is not possible? ( V =330 ~m / s )

Step-by-step solution

n =264 ~Hz , ~V =300 ~m / s For fundamental frequency, n = V 4 = V 4 n = 330 4 264 =0.3125 n =31.25 ~cm For fundamental mode, = 4 other possible lengths are 3 4 , 5 4 , Hence, 62.50 ~m is not possible.
