Answer 2

Answer:

“Band of colors” as in the rainbow is called as Spectrum

Explanation:

The rainbow is the best example of the spectrum. When the white light enters through the spectrum the white light disperses to form different colors. When a white light is extended into a spectrum and it gets transverse by another spectrum recombination of the illumination occurs. And when the white light enters through the spectrum, it shows that white light is the compounding of all seven colors so they break up.
