Derive the expression v = lnfn where ln is the shortest distance between nodes for the nth harmonic.
v = wave speed
ln = shortest distance between nodes for the nthharmonic
fn = frequency of the nth harmonic
The Attempt at a Solution
Is it asking me to take the derivative of the wave speed, which I believe would give me the acceleration of the wave?
wave acceleration = 2*ln
Am I making any sense?
