Question

Using observations from the above actions, explain why we don’t observe "green stars" in nature, though there are indeed stars which emit more green light than other wavelengths

Answer 1

We don't perceive stars as green because stars emit a spectrum of colors, not just one. Though a star may emit more green light, it also emits enough red and blue light that when combined appears white or bluish-white to us due to the way our eyes process light.

Step-by-step explanation:

The reason we don't observe green stars in nature is tied to the way starlight is emitted and the way our eyes perceive color. Stars are basically black bodies that emit a spectrum of light of all colors, not just one. A star that emits more green light will also emit other colors like red and blue. The balance of these colors combined appears white or yellow to our eyes. This is because our eyes are more sensitive to green light and tend to perceive it as white.

While stars do radiate in all colors, including green, the overall emission is more evenly spread across all wavelengths, rather than being concentrated in one area. The perception of combined colors takes into account not only intensity but also the sensitivity of our eyes at different wavelengths.

To explain more simply, there may be a star that emits predominantly green light, but it also emits enough red and blue light to, when combined, appear white or bluish-white to an observer, due to the way our eyes process light.
