velocity - waves
v = frequency/wavelength
frequency - waves
frequency = 1/period
wavelength - standing waves (strings)
λ = (2L)/(n)
wavelength - standing waves (open pipes)
λ = (2L)/(n)
wavelength - standing waves (closed pipes)
λ = (4L)/(n)
frequency - standing waves (strings)
frequency = (n*v)/(2L)
frequency - standing waves (open pipes)
frequency = (n*v)/(2L)
frequency - standing waves (closed pipes)
frequency = (n*v)/(4L)
