Answer 1

Answer #1

For one end closed tube, resonance frequencies are given by, n2 f = 7 n = 1,3,5,... Given, fundamental frequency, fi= - = 341

A.

B.

fn=nfi, v= 338.979m/s f2 = 682.6Hz, L= 338.979 4* 682.6 =0.1242m f3 = 1023.9Hz, L-_338.979 4 * 1023 0 = 0.0828m f4 = 1365.2H2

C.

A resonance tube can be used to measure the speed of sound in air. A tuning fork is held above the opening of the tube and struck, while the far end of the tube is lengthened or shortened. Resonances (loudnesses) are heard at a series of tube lengths, L, which are carefully measured. resonance tube The speed of sound in air is determined by measuring the distance between two consecutive resonances. A data set for a tuning fork with a...

1. a.) A stretched string held by two students has a length of 1.5m and a mass of 0.25kg. How much tension must the two kids pull on the rope to produce waves on the string that would travel 5 m/s? b.) With what frequency must one student shake the string to produce the first standing wave? 2.

Thank you and I appreciate your help and time in advance! L = N (l/4), N = 1, 3, 5 … (1) Where L is the length of the air column and N is an odd integer. When N = 1, the column has a length one quarter of wavelength with a node at the water surface and an antinode at the opening. Then the wavelength L1= (1/4) l, or l= 4L1. (2) When N = 3, with...
