The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky. Each rainbow reflects white light inside its coloured bands, but that is "down" for the primary and "up" for the secondary. [30]
It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
A secondary rainbow is much fainter than a primary one because the intensity of light is reduced. Moonbows, or a lunar rainbow, are a rarer phenomenon that happens when light from the moon is ...
For example, mixing green light (530 nm) and blue light (460 nm) produces cyan light that is slightly desaturated, because response of the red color receptor would be greater to the green and blue light in the mixture than it would be to a pure cyan light at 485 nm that has the same intensity as the mixture of blue and green. Because of this ...

Light spectrum, from Theory of Colours – Goethe observed that colour arises at the edges, and the spectrum occurs where these coloured edges overlap.. Theory of Colours (German: Zur Farbenlehre) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans.
Physical colors are temporary. They exist when light combines with cloudy transparent or translucent media, such as smoke, fog, or a glass prism. They are comprehensible because we know that they result from part of the qualitative division of retinal activity. Light is the external physical stimulus of the retina's activity.
