A ceramic component is heated in an industrial oven. A sensor measures the intensity of the radiation emitted by the component at two different times.
The table includes the wavelength at which the intensity was greatest in each recording.
| Wavelength in μm\mu\text{m}μm | Intensity in recording A in arbitrary units | Intensity in recording B in arbitrary units |
|---|---|---|
| 2 | 8 | 48 |
| 4 | 34 | 92 |
| 8 | 55 | 74 |
| 16 | 24 | 31 |
State which recording was made when the ceramic component was hotter.
Explain how the data support your answer.
