A student measures the distance across four complete wavelengths for waves travelling through the same medium. The results are shown in the table.
| Frequency (Hz) | Distance across four wavelengths (cm) |
|---|---|
| 4.0 | 48 |
| 6.0 | 32 |
Calculate the wave speed at each frequency.
Explain how the results show the relationship between frequency and wavelength.
