Physics Light Part 9 (Sunlight dispersion) Class 8 VIII

TL;DR

Sunlight appears white, but it is actually made up of seven different colors, which can be observed through a prism. This dispersion of light is also seen in the formation of rainbows.

Questions & Answers

Q: What is the color of sunlight?

Sunlight appears white in color, but it is actually made up of seven different colors.

Q: How can we observe the different colors of sunlight?

By passing sunlight through a prism, it can be split into its constituent colors and observed.

Q: What is dispersion of light?

Dispersion of light refers to the splitting of white light into its constituent colors, as seen when light passes through a prism.

Q: How is dispersion of light related to rainbows?

Rainbows are formed when sunlight passes through raindrops in the atmosphere, acting as tiny glass prisms and dispersing the light into its constituent colors.

Summary & Key Takeaways

• Sunlight appears white in color, but it is composed of seven different colors.

• A prism can be used to observe the dispersion of white light into its constituent colors.
