The equation for velocity of waves on a string
The video states that the velocity (v) of a wave moving along a string is related to the strings tension (T) and its mass per unit length (μ). The unit of tension is the Newton (N) and the unit of mass/length is kg/m.
A simple interrogation of the formula v = √(T/ μ) shows that as T increases so too does velocity, whereas if μ increases the velocity decreases.
