Question

A Group Of Four Stars, All The Same Size, Have The Four Different Surface Temperatures Given Below. Which Of These Stars Emits the most red light?

Answer 1

The star with the lowest surface temperature out of the four would emit the most red light because red wavelengths correspond to lower temperatures.

Step-by-step explanation:

The color of light that predominates a star's appearance correlates with its surface temperature, which affects the energy output and color spectrum emitted by the star.

When comparing stars of the same size but with different surface temperatures, we find that the star with the highest temperature tends to emit the most blue light because blue is a shorter-wavelength color indicative of higher energy and higher temperature.

Conversely, the star with the lowest temperature will emit the most red light, as red is a longer-wavelength color and represents a lower temperature. Therefore, out of the four stars mentioned, the one with the lowest surface temperature will emit the most red light.
