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)

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)

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.

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

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 .

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

Two organ pipe open in both end of length 50cm and 50.5 cm when sounded, number of beats per sec is 3. Calculate the velocity of sound in air.

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 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]

An ambulance blowing a siren of frequency 700 Hz is travelling towards a wall with a speed 2 m(s)^-1.Calculate the number of beats heard in one second by the driver of the ambulance.(velocity of sound = 350 m(s)^-1 )
