Text Solution

Verified by Experts

The correct Answer is:
A

`v=f_(1) lamda_(1)=f_(2)lamda_(2)rArr 512xx4L=f_(2)xx2L`
`rArr f_(2)=1024Hz`

An open organ pipe filled with air has a fundamental frequency 500 Hz. The first harmonic of another organ pipe closed at one end and filled with carbon dioxide has the same frequency as that of the first harmonic of the open organ pipe.

A hollow metallic tube of length L and closed at one end produce resonance with a tuning fork of frequency n. The entire tube is then heated carefully so that at equilibrium temperature its length changes by l . If the change in velocity V of sound is v, the resonance will now produced by tuning fork of frequency :-

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic ) of an air column of length 75 cm inside a tube closed at one end. The string also generates 4 beats//s with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces to 2 per second. Assuming the velocity of sound in air to 340 m//s , the frequency n the tuning fork in H_(Z) is (a) 344 (b) 336 (c ) 117.3 (d) 109.3

An organ pipe closed at one end has fundamental frequency of 1500 Hz. The maximum number of overtones generated by this pipe which a normal person can hear is

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.
