A point T stays in the same location when it is reflected over line l.

What can you conclude about point T? Where must point T be located in the diagram?

### Equation for the Speed of a Wave on a String

The speed \( v \) of a wave traveling along a stretched string is determined by the tension \( T \) in the string and the linear mass density \( \mu \) of the string. The relationship is given by the equation:

\[
v = \sqrt{\frac{T}{\mu}}
\]

Where:
- \( v \) is the wave speed.
- \( T \) is the tension in the string, measured in newtons (N).
- \( \mu \) is the linear mass density, defined as the mass per unit length of the string, measured in kilograms per meter (kg/m). 

This equation illustrates that the speed of the wave increases with greater tension and decreases with greater mass density. Understanding this relationship is crucial in fields such as physics and engineering, as it applies to various practical applications, including musical instruments and mechanical vibrations.
