List two conditions necessary to observe a rainbow.
List two conditions necessary to observe a rainbow.
Show Hint
Rainbows occur when sunlight is refracted, reflected, and dispersed by water droplets in the atmosphere.
Updated On: Jan 13, 2026
Show Solution
Solution and Explanation
Refraction and dispersion of light necessitate water droplets or an equivalent transparent substance. The viewer's angle must be approximately 42° relative to the sun's rays and water droplets.
