An organ pipe of length L open at both ends is found to vibrate in its first harmonic when sounded with a tuning fork of 480 Hz. What should be the length of a pipe closed at one end,so that it also vibrates in its first harmonic with the same tuning fork?

A sonometer wire is vibrating in resonance with a tuning fork.Keeping the tension applied same,the length of the wire is doubled.Under what conditions would the tuning fork still be in resonance with the wire?

A metre-long tube open at one end, with a movable piston at the other end, shows resonance with a fixed frequency source (a tuning fork of frequency 340 Hz) when the tube length is 25.5 cm or 79.3 cm. Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected.

Find the relations for the first harmonic produced by an open end organ pipe and a closed end organ pipe.

A resonance pipe is open at both ends and 30 cm of its length is in resoance with an external frequency 1.1 kHz.If the speed of sound is 330 m s^(-1) which harmonic is in resonance?

A pipe 20 cm long is closed at one end. Which harmonic mode of the pipe is resonantly excited by a 430 Hz source ? Will the same source be in resonance with the pipe if both ends are open? (speed of sound in air is 1340 m s^-1 )
