# The velocity of transverse waves on a string

1. A violin string is 35 cm long between its fixed ends and has a mass of 2.0g. The string sounds the note A4 (440 Hz) when played.

## Homework Equations

v=$\sqrt{}F/ρ$

## The Attempt at a Solution

I calculated ρ, mass per unit length, to be .0057 kg/m but do not know how to find the force that I need to plug into the equation.

$$f = \frac{v}{2 L}$$
