A tuning fork has got a frequency equal to the fundamental frequency of 25 cm length of a sonometer wire.Without change the load,if the legth of the wire is increased to 25.5 cm then 3 beats are heard per secondwhen the fork and wire are made to vibrate together.Calculate frequency of the tuning fork.

The fundamental frequency of stretched wire of length 50 cm is in unision with the frequency of a tuning fork.If the length is increased by 0.5 cm.4 beats per second are formed.Find the frequency of the tuning fork.

If the tension in a sonometer wire is increased by 2.5 N,its frequency increases in the ratio 3:2.What was the original tension?

A sonometer wire is under tension of 40 N and the length between the two bridges is 60 cm.A one metre long wire of the sonometer has a mass of 1.0 g.Deduce the speed of transverse waves and the frequency of the second harmonic.

When two tuning forks when sounded together,20 beats were produced in 8 seconds .After loading one of the forks with a littile wax,they produce 32 beats in 8 seconds.If the unloaded fork had a frequency of512 Hz,calculate the frequency of the other.

Two tuning forks when sounded together give 4 beats per second.if one of them is in unison with 96 cm length of a monochord under constant tension and the other with 97 cm length of the same string,find the frequencies of the fork.

The length between two bridges of a sonometer wire is L, tension is T and the fundamental frequency is N, if the length between the bridges and tension both are doubled, explain if there is any change in fundamental frequency.

Two tuning forks produce 4 beats per second when sounded together.On loading one of them the number of beats become 2 per second.Find the frequency of the loaded fork if that of the other is 510 Hz.

A tuning fork A of frequency 384 Hz gives 6 beats per second when sounded with another tunig fork B.On loading B with a littile wax,the number of beats per second becomes 4.What is the frequency of B?

The length of a sonometer wire is 0.75m and density 9xx10^3 kgm^(-3) . It can bear astress of 8.1xx10^8 Nm^(-2) without exceeding the elastic limit Calculate the fundamental frequency that can be produced in the wire.

A string 25 cm long and having a mass of 2.5 g is under tension.When the string is vibrating in its first overtone and air in a 40 cm long closed pipe in its fundamental frequency 8 beats per second are heard.it is observed that decreasing the tension in the string decreases the beat frequency.Find the tension in the string.[Velocity of sound is 320 m/s]
