Here is а link tо Desmоs Here is аnоther formulа that we used that is slightly different than the one in the formula sheet above a) If you are planning on using a string to generate a sound wave, describe two things that you could do to that string in order to change the frequency at which it would resonate. b) If a closed air column is 1.75m long and it is in a room that is 23 degrees Celsius; find the frequency and the wavelength of the 3rd and 4th harmonics. c) If a string is resonating in its second harmonic on a 15 degree Celsius day at a frequency of 550 Hz, how long is the string?
