(a) Determine the length of an open organ pipe that emits F (349 Hz) when the temperature is 15°C.
.487m
(b) What are the wavelength and frequency of the fundamental standing wave in the tube?
λ = ??? m
f = 349 Hz
(c) What are λ and f in the traveling sound wave produced in the outside air?
λ = ??? m
f = 349Hz

this is just like calculating the wave length and frequency of normal waves, BUT this has heat involved. Heat should clue you in on the concept of pressure. Pressure is directly related to sound waves, because sound waves travel through air (usually) and thus air pressure is very important.
displacement function: displacement(x, freq.) = displament amplitude * cosine(kx - wt)
w = angular frequency which w = 2 pi / period
k = angular wave number which k = 2 pi / wave length
you can do the math, just look up displacement function and pressure-variation funtion in your book, because I am a little rusty on my physics.
