Question

• A. Dispersion of incident light first, then reflection internally and finally refraction causes rainbow.
• B. Water droplets act like small prisms
• C. Sometimes there is formation of two rainbows in the sky
• D. Rainbow is formed in the direction of the sun

Answer 1

The correct option is D Rainbow is formed in the direction of the sun

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 arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
