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.

Show that the fundamental frequency for the open pipe is twice that for the closed pipe of the same length.

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?

What is the relation between the fundamental frequency and overtones in a closed pipe?

The tension and diameter of a sonometer wire of fundamental frequency n are doubled and density is halved.Its fundamental frequency will be

A sonometer wire emits a note of frequency 150 Hz.What will be the frequency of the note emitted by it if its tension increaeed in the ratio 9:16 and the length is doubled?

The length of a metal is l_1 when the tension in it is T_2 and is l_2 when the tension is T_2 . Find the original length of the wire.

If the tension of the wire is increased four times and its length reduced to half the original length the frequency of vibration

You are asked to prepare open organ pipe having fundamental frequency 240.What should be the length of the pipe?[velocity of sound in air =330 m/sec)

What is the fundamental frequency at 20^@C of an open pipe of length 120 cm? The velocity of sound in air at 20^@C is 343 m//s .

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]
