To understand what caused the missing colors on the electromagnetic spectrum for the sun, we can eliminate some options based on basic knowledge of how the sun produces light.
Option C, "the heat of the sun vaporizes those colors," can be eliminated because the colors in the electromagnetic spectrum are not vaporized by the sun's heat. Heat can affect the intensity of light, but it does not vaporize colors themselves.
Option D, "they were admitted when the sun," seems to have a typographical error, so it is not a valid choice.
Now let's consider the remaining options:
Option A, "they were absorbed when leaving the sun," is a plausible explanation. When light is emitted from the sun's surface, it passes through the sun's atmosphere before reaching us on Earth. The sun's atmosphere, particularly its outer layer called the chromosphere, contains various elements such as hydrogen, helium, and smaller amounts of other elements. These elements can absorb specific wavelengths of light, resulting in missing colors in the spectrum that reaches us. This phenomenon is known as absorption.
Option B, "those colors are not produced by the sun," is also a valid explanation. The sun emits a broad range of colors across the electromagnetic spectrum, but it does not produce specific colors in certain regions of the spectrum. For example, the sun emits a lot of visible light, which includes colors like red, orange, yellow, green, blue, indigo, and violet. However, there are certain colors outside this range, such as ultraviolet or infrared, that the sun does not emit as strongly.
In summary, the most likely explanation for the missing colors on the electromagnetic spectrum for the sun is a combination of options A and B. Some colors are absorbed by the sun's atmosphere, while other colors are simply not produced in significant quantities by the sun itself.
