To find the speed of a wave, you can use the formula:
\[
\text{Speed} = \text{Wavelength} \times \text{Frequency}
\]
Given:
- Wavelength (\(\lambda\)) = 4.5 meters
- Frequency (\(f\)) = 100 hertz
Now, plug in the values:
\[
\text{Speed} = 4.5 \, \text{m} \times 100 \, \text{Hz} = 450 \, \text{m/s}
\]
Thus, the speed of the wave in the wire is **450 m/s**.
\[
