Homework Help: physics. HELP PLEASE

One method for measuring the speed of sound uses standing waves. A cylindrical tube is open at both ends, and one end admits sound from a tuning fork. A movable plunger is inserted into the other end at a distance L from the end of the tube where the tuning fork is. For a fixed frequency, the plunger is moved until the smallest value of L is measured that allows a standing wave to be formed. Suppose that the tuning fork produces a 449-Hz tone, and that the smallest value observed for L is 0.202 m. What is the speed of sound in the gas in the tube?
