A metal component is heated in a laboratory. Measurements are taken at two temperatures.
Explain why the component can be seen to glow at 1000 °C but not at 500 °C. Use the data in your answer.
| Temperature of component | Relative intensity of emitted radiation | Wavelength of peak intensity |
|---|---|---|
| 500 °C | 2.4 | 3.7 μm |
| 1000 °C | 18 | 2.3 μm |
