task 1: color and temperature
you have already learned about a blackbody. how is the temperature of a blackbody related to its color?

Explanation:

A blackbody emits electromagnetic radiation across a range of wavelengths. As its temperature increases, the peak of the emitted radiation shifts to shorter wavelengths. Shorter wavelengths correspond to higher - energy light. For example, at lower temperatures, a blackbody emits more in the infrared (not visible to the human eye as color). As the temperature rises, it starts to emit in the red part of the visible spectrum (longer visible wavelengths), then as the temperature continues to increase, it moves to yellow (shorter than red), and at very high temperatures, it emits white (a combination of all visible wavelengths) or even blue (shorter wavelengths). So, the color of a blackbody is an indication of its temperature, with hotter blackbodies having colors corresponding to shorter - wavelength (higher - energy) light.

Answer:

The temperature of a blackbody is related to its color such that as the temperature increases, the color of the blackbody changes from longer - wavelength (lower - energy, like red) to shorter - wavelength (higher - energy, like blue) light.
