## Homework Statement

A wire is strung tightly between two immovable posts. Decide whether the speed of the transverse wave on this wire would increase, decrease, or remain the same when the temperature increases. Ignore any change in the mass per unit length of the wire.

## Homework Equations

$$v=\sqrt{\frac{F}{m/L}}$$

$$\Delta L=\alpha L_{0} \Delta T$$

## The Attempt at a Solution

In the second equation we see that as the temperature increases the length expands. In the first equation, bigger length would imply that the speed increases. But the answer given in the textbook is "Decreases". Why?
