Question

6 Read the following and answer any four questions from 6(i) to 6(v)
A rainbow is one of the most spectacular natural light shows observed in the
sky. A number of scientist an mathematician including Aristotle, Bacon,
Theodoric, Descartes, Newton, Young, Airy and Mile have worked on the
explanation of various observation on rainbows.
To understand the formation of rainbow one should actually study the
refraction, internal tefraction, dispersion and total deviation of white light by
the spherical water drop.
A rainbow is produced when sunlight falls and gets diverted to the eyes of the
observer due to a large number water droplets in the sky on a rainy day.
In addition to primary rainbow there is a secondary rainbow. It occurs in the
same manner as the primary rainbow but due to two internal reflections. In
nature we can observe only primary and secondary rainbows. Higher order
rainbows are never seen since they are weaker than i) the background sky
brightness ii) the light reflected from the outside surface of the drops and iii)
the light transmitted through the process with no internal reflection.
6(i) What is refraction?
6(ii) List two essential conditions for observing rainbow.
