Using the accepted value of sound from equation (1), calculate the wavelength of the 500 hz sound wave. 1500= 0.69 units m a. using this value of wavelength and equation (3), calculate the true value of n for the longest standing wave tube length in your standing wave experiment (round n to the nearest higer integer). largest n=_ 3_ (in your experiment) b. make a sketch (on an attached sheet of paper) of what the "largest n" standing (molecular displacement) wave "looks like" inside the tube (at a single point in time). remember, an open ended tube requires the displacement wave ends at an "antinode". i. make sure your drawing is consistence with "n" from question a. ii. make sure to label nodes and anti-nodes iii. show the length of the tube in terms of multiples of n2 iv. show a sine wave indicating the amount of displacement v. finally, add arrows showing the relative amount and direction of longitudinal molecular displacement along the length of the tube.
