c) Answer:

A rainbow is caused by sunlight and atmospheric conditions.

Explanation:

Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

d) Answer:

A Newton disc is a disc with segments in rainbow colours.

Explanation:

When the disc is rotated, the colors fade to white; In this way Isaac Newton demonstrated that white light is a combination of the seven different colours found in a rainbow. ... This property is based on the principles of dispersion of light.
