1. The problem statement, all variables and given/known data
to determine the c(end correction ) of sound wave of single end closed tube, the equtaion l +c= (lambda/4 ) is used , i dont understand the gradient is v/4 , then how does the author come up with the speed of sound in air is v=4 ?
2. Relevant equations
3. The attempt at a solution
