1 State the conditions under which a rainbow can be seen 2 Explain the formation of a primary rainbow. For which angular range with the horizontal is it visible
Answers
Answer:
the rainbow is formed from the dispersing of light from the water vapour
Answer:
There are two important conditions must be met to see the rainbow
Sunrays as a white light and water droplets present in the sky.

The rainbow is a usual phenomenon that was appeared by sunlight through a thin, visible screen of tiny ice crystal present in the sky. When the Sunrays passes through the water droplets present in the sky. The droplets will shine like a prism.
The visible angular range of the primary rainbow is 40-42 degrees. Exceeding this angle, the rainbow won't be visible. The visible range of secondary rainbow is 50-53 degrees. The rainbow has VIBGYOR color. There will be two strips having red and orange. The other colors are yellow, green, blue, indigo, and violet visible due to reflection and dispersion.
