A detector records four groups of electromagnetic waves. The table gives information about the position of each group in the electromagnetic spectrum.
| Wave | Position in the electromagnetic spectrum |
|---|---|
| P | Immediately lower in frequency than ultraviolet |
| Q | Immediately higher in frequency than ultraviolet |
| R | The highest-frequency named group |
| S | Immediately lower in frequency than infrared |
Which two waves are ionising?
Explain how absorption of these waves by body tissue can increase the risk of cancer.
