Final answer:
Blue stars are the hottest among different colored stars due to the shorter wavelengths of blue light indicating higher temperatures.
Step-by-step explanation:
The color of a star is a key indicator of its temperature. When observing stars, the ones that glow blue or blue-white are the hottest stars, while the ones that appear red are cooler. Therefore, if considering stars of different colors, such as red, yellow, orange, and blue, the blue star would carry the greatest amount of energy as it indicates a higher temperature. The physics behind this is related to the fact that shorter-wavelength light, like blue, is an indicator of a hotter source compared to longer-wavelength light like red. This principle is rooted in the science of blackbody radiation, where the peak emission frequency shifts to shorter wavelengths as the temperature increases.
