1.	b. A raibow is the combined effect of therefraction, dispersion, and total internalreflection of light.
Answer» A rainbow is caused by combined effects of reflection, refraction, and dispersion of light. This is a natural climatic phenomenon, often observed after a shower of rain. Sunlight while pass-through droplets of water produce a spectrum of light that appears in the sky. It takes the form of a circular arc with multiple colour.arc. Rainbows produced by sunlight always found to arise opposite the sun in the sky. Although rainbow is formed in full circle in the sky, we normally see only an arc formed by illuminated droplets.
