A laboratory instrument records electromagnetic radiation from light sources. It can be fitted with sensor P or sensor Q.
The table shows the range of wavelengths that each sensor can record.
| Sensor | Shortest wavelength recorded in nm\text{nm}nm | Longest wavelength recorded in nm\text{nm}nm |
|---|---|---|
| P | 350 | 650 |
| Q | 450 | 750 |
For this question, visible light has wavelengths from 400 nm400\ \text{nm}400 nm to 700 nm700\ \text{nm}700 nm.
Compare the radiation that sensor Q can record with the radiation that sensor P can record.
