Prisms, Rainbows and Soap Bubbles
Transcript of Prisms, Rainbows and Soap Bubbles
light from the sun enters a droplet of rain, causing the colors of light to spread Bubbles The reason that soap bubbles are colored has to do with the physics of light
We see light as violet, blue, green, yellow, orange and red
The bubbles are a transparent medium through which light rays enter and bend Prisms Over 300 years ago, Sir Isaac Newton passed a beam of white light through a prism.
A prism is a triangular piece of glass, which allows light to spread out into a band of six colors
These colors are red, orange, yellow, green, blue and violet
Newton then sent this light through a second prism where the light became white once again Refraction
Materials you will need:
• A Glass
• White Card
• Piece of Cardboard
• A ruler
• Colored pencils or crayons
• Hole Punch (optional)
• String (around 2' or 24") How to do Rainbow Spinners Demonstration Refraction is when a wave enters a new material and bends.
The colors of the spectrum are interpretations of different wavelengths and frequencies.
When white light passes through a prism the different spectrum color's wavelengths bends differently, separating each color making them visible to see.
