The Colors of the Rain
- Brand: Unbranded
Description
If the Sun were a laser emitting parallel, monochromatic rays, then the luminance (brightness) of the bow would tend toward infinity at this angle (ignoring interference effects). A rainbow shows up as a spectrum of light: a band of familiar colors that include red, orange, yellow, green, blue, and violet. The result of this is not only to give different colours to different parts of the rainbow, but also to diminish the brightness.

However, remember that there is also a whole range of colours, so many that we cannot distinguish them all with the naked eye. If, however, the word rainbow is used inaccurately to mean spectrum, it is the number of main colours in the spectrum.The light that reflects off the drop, exits from the back, or continues to bounce around inside the drop after the second encounter with the surface, is not relevant to the formation of the primary rainbow.

Red (the longest wavelength at around 780 nm) through to Violet (the shortest wavelength in the sequence at 380 nm). Seawater has a higher refractive index than rain water, so the radius of a "rainbow" in sea spray is smaller than that of a true rainbow. It is a vertical arrangement of six bands, each representing a different aspect of Buddhism, from kindness to moderation, blessings to wisdom.
His ideas were picked up and elaborated upon by the Roman philosopher Seneca the Younger in his Book 1 of Naturales Quaestiones around 65 AD. The light at the back of the raindrop does not undergo total internal reflection, and some light does emerge from the back. The shadow of the photographer's head at the bottom of the photograph marks the centre of the rainbow circle (the antisolar point).

Further red of the first supplementary rainbow overlaps the violet of the primary rainbow, so rather than the final colour being a variant of spectral violet, it is actually a purple. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. But since the Sun's luminance is finite and its rays are not all parallel (it covers about half a degree of the sky) the luminance does not go to infinity.This is because each raindrop is a sphere and it scatters light over an entire circular disc in the sky.
