If the speed of sound 336m/s in air, then find the shortest length of the one end closed tube that will resonate with a fork of frequency 21oHz.

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 velocity of sound in air is 332 m/s.The frequency of the fundamental node of an open pipe 50 cm long will be

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.

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 .

A source of sound is movig with a speed 220 m(s)^-1 towards a stationary target.While moving,it emits a wave of frequency 1000 Hz.Some of the sound reaching the target get reflected back to the source as echo.Calculate the (i)frequency of sound as detected by the target and (ii)the frequency of echo as detected by the source?

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)

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?

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.

Two children are at opposite ends of an aluminium rod. One strikes the end of the rod with a stone. Find the ratio of times taken by the sound wave in air and in aluminium to reach the second child.
