Our sun is what scientists call a "yellow-green star." Does it emit energy in the frequency of red light?
I have no idea!
Yes, it emits at ALL visible frequencies, including red. That is why you see all the colors in a rainbow. The sun emits more green than other frequencies.

To answer your question, we need to understand the concept of spectral classification. Scientists classify stars based on their temperatures, which determine the predominant color of light they emit. The color of a star depends on its surface temperature, with hotter stars emitting bluer light and cooler stars emitting redder light.
The sun, classified as a yellow dwarf star, emits energy in a broad range of frequencies, including red light. However, the sun's peak emission lies in the visible range, specifically the yellow-green part of the electromagnetic spectrum. This is why scientists refer to it as a "yellow-green star."
To get a more in-depth answer to your question, you can explore the field of astrophysics, particularly stellar classification and the sun's electromagnetic spectrum. By studying the sun's emission spectrum, scientists can precisely determine the frequencies of light it emits.
