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`.

What is the velocity of sound in air at 0^@C .

In a organ pipe closed at one and at 20^@C the fundamnetal frequency 256 HZ. What is the length of the pipe (velocity of bound in air at 0^@C is 332 m/s.

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 frequency of fundamental note of 0.2 metre long open pipe.Velocity of sound in air is 322 m/s

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

Two open pipes of different lengths are producing their fundamental tones simultaneously and the number of beats per second is 5.if the shorter pipe has fundamental frequency 250 Hz,what is the length of the longer pipe?(velocity of sound = 340m/s)

Two organ pipes one open at both ends,and the other open at one end only give their fundamental noteswhose frequencies differ by 25 vibration per second.The length of the open pipre is 96 cm.Calculate the length of the closed pipe if the velocity of sound in air is 330 m(s)^-1 .

At what temperature will the velocity of sound in air be double than the velocity in air at 22^@C ?

A train whistling while approaching a railway platform with a speed of 90 km(s)^-1 .The frequency of sound of the whistle is 600 Hz.If the velocity of sound in air is 325 m(s)^-1 ,calculate the apparent frequency of the sound of the whistle as heard by an observer standing on the platform.

The length of a cylindrical glass tube is 30 cm.the velocity of sound in air is 330 m(s)^-1 .What is the fundamental frequency of vibration of the air coloumn if (i)both ends of the tube are open and (ii)open end is closed and flat?
