A student measures the peak wavelength of the radiation emitted by a heated surface at two temperatures.
| Temperature in K | Peak wavelength in μm |
|---|---|
| 500 | 5.8 |
| 700 | 4.1 |
The surface is then heated to 900 K.
Predict how the peak wavelength and the total intensity of the radiation emitted at 900 K compare with those at 700 K. Explain your predictions.
