Question: 1 calculate the approximate speed of sound in the lab...

Question details

1. Calculate the approximate speed of sound in the lab assuming that T = 22◦C using Eq. 2.2. 2. Using your answer from part (a), nd the highest mode number for a resonant wave that can exist in an open-closed sound tube of length 90 cm for frequencies, 293.7 Hz, 329.6 Hz, 392 Hz, 493.9 Hz, 512 Hz and 523.3 Hz. 3. Draw pressure standing waves in a sound tube for mode numbers of 1, 3 and 5. v = (331m/s)Square root ( T/273K) .......Eq. 2.2 Please, solve questions 2 and 3. Thanks
