A monitoring system sends waves along a steel railway track. The wave speed in the track remains constant when the source setting is changed.
| Source setting | Measurement | Value |
|---|---|---|
| first | time for 20 complete oscillations | 0.0080 s |
| first | wavelength | 2.0 m |
| second | period | 0.00025 s |
Calculate the wavelength of the waves at the second source setting.
