A museum display shows the groups of the electromagnetic spectrum. Three of the labels have been replaced by the letters P, Q and R. The table gives a clue to each missing group.
| Label | Clue |
|---|---|
| P | It is next to ultraviolet in the spectrum and has a lower frequency than ultraviolet. |
| Q | It is next to ultraviolet in the spectrum and has a higher frequency than ultraviolet. |
| R | It is next to microwaves in the spectrum and has a shorter wavelength than microwaves. |
Give the name of each of the three groups represented by P, Q and R.
Explain how the wavelength of Q compares with the wavelength of P.
