Information:
The frequency of the note [tex]{\rm F}_4[/tex] is [tex]f_F[/tex].
1. If an organ pipe is open at one end and closed at the other, what length must it have for its fundamental mode to produce this note at a temperature of T? The speed of sound is [tex]v_s[/tex].
I used the equation [tex]f_n = \frac{nv}{4L}[/tex]. Plugging in known values resulted in [tex]L = \frac{1}{4}\frac{v_s}{f_F}[/tex]. This is correct.
2. At what air temperature will the frequency be f? (Ignore the change in length of the pipe due to the temperature change.)
I have no idea how to start this.
