Homework Statement
What is the wavelength of the lowest note that can resonate within an air column 42 cm in length and closed at both ends.
Homework Equations
Given: l = 42 cm
n = 1
Required: [tex]\lambda[/tex]
Analysis: l = [tex]\frac{n\lambda}{2}[/tex]
therefore [tex]\lambda[/tex] = [tex]\frac{2l}{n}[/tex]
I don't know how this came to be, could someone please explain.
I've just gone back to high school after 15 years and would appreciate if you could also forward me on to some good links for rules for mathematical equations such as these.
Thanks
Scott
