Rainbowe

A rainbowe is a meteorological phenomenon that is caused bi reflection, refraction an dispersion o licht in watyer draplets resultin in a spectrum o licht appearin in the sky. It taks the form o a multicoloured circular arc. Rainbowes caused bi sunlicht ayeweys appear in the section o sky directly opposite the sun.
Rainbowes can be full circles. Houiver, the observer normally sees anerly an arc formed bi illuminatit draplets abuin the grund,[1] an centred on a line frae the sun tae the observer's ee.
In a primary rainbowe, the arc shaws reid on the ooter pairt an violet on the inner side. This rainbowe is caused bi licht bein refractit whan enterin a draplet o watter, then reflectit inside on the back o the droplet an refractit again whan leavin it.
In a dooble rainbowe, a seicond arc is seen ootside the primar arc, an haes the order of its colours reversed, wi reid on the inner side o the arc. This is caused bi the licht bein reflectit twice on the inside o the draplet afore leavin it.
