Question

18.2 second for some answer idk

This is very advanced so if you can’t do it don’t try it. From UCLA

(16.3.40) If you are handed an open-open pipe, you can turn it into an open-closed pipe by covering one of the open ends with the palm of your hand. (a) If a certain pipe of length 0.35 m is open at both ends, what is the second lowest frequency that can be produced both when the pipe is open at both ends, and also when one of the ends is covered? Take the sound speed to be 345 m/s. (b) For the frequency you found in part (a), sketch the pressure amplitude variation in the pipe for the open-open case. (c) For the frequency you found in part (a), sketch the pressure amplitude variation in the pipe for the open-closed case.

Answer 1

(a) -for Pipe ơpem at both end 2x 0.3S b Biven lay 4x 0 35 forr pipe spen at both enl
