A length of organ pipe is closed at one end.
If the speed of sound is 344 m/s, what length of pipe is needed to obtain a funda- mental frequency of 70 Hz? Answer in units of m.

• Physics -

70*lambda=340 solve for lambda
then, length of pipe is 1/4 lambda

• Physics -

explain Lambda? I was sick and missed class?
