Answer 1

Answer:

Rainbows appear in seven colors because water droplets break white sunlight into the seven colors of the spectrum (red, orange, yellow, green, blue, indigo, violet). You can only see a rainbow if the Sun is behind you and the rain in front. The main rainbow becomes visible at an angle of around 40" from the horizon.

Answer 2

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

There are seven colors in the rainbow: red, orange, yellow, green, blue, indigo and violet.
