The second overtone of an open pipe is in resonance with the first overtone of a closed pipe of length 2 m. Length of the open pipe is

Two wires are fixed in a sonometer. Their tensions are in the ratio 8 : 1. The lengths are in the ratio 36 : 35. The diameters are in the ratio 4 : 1. Densities of the materials are in the ratio 1 : 2. If the higher frequency in the setting is 360 Hz, the beat frequency when the two wires are sounded together, is

If v is the speed of sound in air, then the shortest length of the closed pipe which resonates to a frequency v, is

In 1 m long open pipe, what is the harmonic of resonance obtained with a tuning fork of frequency 480 Hz?

A string of length 2 m is fixed at both ends. If this string vibrates in its fourth normal mode with a frequency of 500 Hz, then the waves would travel on it with a velocity of

The fundamental frequency of a sonometer wire is v. If its radius is doubled and its tension becomes half, the material of the wire remains same, the new fundamental frequency will be

In open organ pipe, if fundamental frequency is v, then the other frequencies are

An organ pipe, open at both ends produces 5 beats/s, when vibrated with a source of frequency 200 Hz. The second of the same pipe produces 10 beats/s with a source of frequency 420 Hz. The frequency of source is

An organ pipe open at one end is vibrating in first overtone and is in resonance with another pipe open at both ends and vibrating in third harmonic. The ratio of length of two pipes is

An open pipe is suddenly closed at one end with the result that the frequency of third harmonic of the closed pipe is found to be higher by 100Hz than the fundamental frequency of the open pipe. The fundamental frequency of the open pipe is
