Final answer:
As the temperature of a blackbody increases, the peak of its radiation curve moves towards shorter wavelengths.
Step-by-step explanation:
The temperature of a blackbody radiator affects the wavelength of light it emits. As the temperature increases, the peak of the radiation curve shifts towards shorter wavelengths. This means that the most intense wavelength of light emitted by the blackbody radiator moves towards the visible and ultraviolet parts of the spectrum. For example, at lower temperatures, the peak may be in the infrared range, while at higher temperatures, it may shift towards the visible range.
