Why in secondary rainbow have upper color is violet and lower color is red |
| Answer» The sequence for rainbow colors is always the same – red, orange, yellow, green, blue, indigo and violent – because different colors of light have different wavelengths. Red always appears first, forming the rainbow\'s outer arc, because it has the longest wavelength of around 650 nanometers. Because light bends at 42 degrees to produce this color, you can almost always see it in a rainbow, even if the other colors in the rainbow are not as obvious. | |
