Final answer:
Wien's law states that the temperature of a blackbody is inversely proportional to the wavelength at which it emits the greatest intensity of radiation. Applying Wien's law to the connection between the color and temperature of stars, we can see that hotter stars emit more blue light and ultraviolet radiation, while cooler stars emit more red light and infrared radiation. Therefore, the color of a star provides a measure of its intrinsic temperature, with blue stars being hotter and red stars being cooler.
Step-by-step explanation:
Wien's law states that the temperature of a blackbody is inversely proportional to the wavelength at which it emits the greatest intensity of radiation.
Applying Wien's law to the connection between the color and temperature of stars, we can see that hotter stars emit more blue light and ultraviolet radiation, while cooler stars emit more red light and infrared radiation.
Therefore, the color of a star provides a measure of its intrinsic temperature, with blue stars being hotter and red stars being cooler.
