A student performs a ripple tank experiment to study water waves at different depths. The table below shows the typical data collected during the experiment:
| Water depth (mm) | Wave speed (cm/s) | Wavelength (cm) |
|---|---|---|
| 8.0 | 28.0 | 5.6 |
| 2.0 | 14.0 | 2.5 |
The student suggests three conclusions from the data:
Which conclusions are correct?
1, 2, and 3
1 and 2 only
1 and 3 only
2 and 3 only
237 exam-style questions on CIE IGCSE Physics General properties of waves, covering General properties of waves. Each one has a worked solution and a mark scheme showing where the marks go.
