$\small \bold{ \underline \blue {angle \: of \:deviation}}$

the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another.

When a beam of light enters a prism, it gets refracted and splits into its seven constituent colours. This splitting of the light ray occurs because of the different angles of bending of each colour. Hence, each colour passing through the prism bends at different angles with the respect to the incident beam

$\bold {\underline \green{rainbow}}$

The sun needs to be behind the viewer. The sun needs to be low in the sky, at an angle of less than 42° above the horizon. The lower the sun in the sky the more of an arc of a rainbow the viewer will see. Rain, fog or some other source of water droplets must be in front of the viewer.
