A standing wave with n=7 in a pipe 0.50 m in length and filled with air has a top open to the air and the bottom closed? I want to calculate the frequency created by this standing wave assuming the air is at room temperature. How can I do this?

Solution
λ = c / f = wave speed
Wave length=7
Height=0.50m
Convert the wavelength to meters before using λν = c
=7.00 x 108 m ¯1
Applying the formula, λ = c / f, where by c=height,
Wavelength==7.00 x 108 m ¯1
F= λ /c=7.00 x 108 m ¯1 /0.5
Answer,F=14 x108 Hz.
