Question

Estimate in mm your uncertinity in locating the position of a resonance level. Are the resonances " sharp" (located at a single point)? what is the longest wavelength of sound that could produce a standing wave in the resonance tube? (Assume v = 340 m/s ) what frequency is this ? if the air tube were 50 c , what would be the velocity of the sound in the tube ? for fork 1 = 1024 hz what would the wave length be? where would the first resonance be located?

Explanation / Answer

longest wavelenght -> L = lambda/4 lambda = 50 * 4 = 200cm f= v / lambda = 340 / 2 = 170Hz at f=1024hz v=340m/s lambda= 340/1024 = 33.2cm first resonance is located .2 cm from top
