For a string that vibrates in its second harmonic mode, at what point on the string is the wave speed the fastest?
A: the speed is the same at any point on the string

is this because v depend on the medium? How do I know when v is max at the eq position vs when v depends on the medium only?

the speed of the wave (wave speed) is always the same, unless it changes the medium it is in.

however, the speed of the displacement of the wave particles is diffferent at different times/points on the string.
