Answers
Explanation:
There are seven colors in the rainbow: red, orange, yellow, green, blue, indigo and violet. The acronym “ROY G. BIV” is a handy reminder for the color sequence that makes up the rainbow. Portrait of Sir Isaac Newton by Godfrey Kneller.
The electromagnetic spectrum covers a very wide range of frequencies/wavelengths of radiation, and part of this range is visible light, which for most persons with normal vision begins with red and ends with violet. But the 7 colors usually assigned to the rainbow, (Red, Orange, Yellow, Green, Blue, Indigo, and Violet) are just arbitrary designations. There are actually millions of colors individually discernable by the human eye. There are many different forms of red, for example. The 7 colors we usually assign are just average values within that visible range.
