Colours of Light by 2E1 Edgar Wong

How are colors produced?
Colors are produced when a light source hits a prism, which separates the white light into its separate colors are called dispersion.

How to get rainbow colors and to recombine the colors again?
Place a second prism positioned in a way that each other’s points are facing away from each other. Shine the light through both prisms.

What are primary colors?
The three primary colors are the minimum number of colors that can be mixed to make the greatest number of other colors. The primary colors cannot be made by mixing other colors.

Effects of mixing of colors.
When you mix colors together, you will get a different color. If you mix the three primary colors together, you get white.

What do you learn about that particular topic?
I’ve learn about the dispersion of white light by a prism and more about the primary colors.

Summarize the key points of that topic.
Colors, they are produced by white light hitting prisms, when lights separates its called dispersion. Placing two prisms facing away from each other can get and recombine colors. When mixing colors together, you get a different color.

Anything interesting to add?
The spectrum consists of: Red, Orange, Blue, Yellow, Green, Indigo and Violet.
Prisms separate the colors already present in the white light.
