The table contains proposed descriptions and values for wavelength, frequency, and the phase difference between two adjacent points on a progressive wave that are in anti-phase.
Which row in the table is correct?
| Wavelength | Frequency | Phase difference | |
|---|---|---|---|
| A | Distance between a crest and the adjacent trough | Number of complete wave cycles passing a point per second | π rad\pi\text{ rad}π rad |
| B | Minimum distance between two points oscillating in phase | Number of complete wave cycles passing a point per second | π rad\pi\text{ rad}π rad |
| C | Minimum distance between two points oscillating in phase | Time taken for one complete wave cycle to pass a point | 2π rad2\pi\text{ rad}2π rad |
| D | Distance between a crest and the adjacent trough | Time taken for one complete wave cycle to pass a point | π2 rad\displaystyle \frac{\pi}{2}\text{ rad}2π rad |
