The experiment ahead of you 
Color (Vision)

 

 

:Objective

Understanding that colors are part of the visible light spectrum

:Introduction

Visible light is the fraction of the electromagnetic spectrum that the human eye can perceive and translate into images

These wavelengths are in the range of 390-750nm. After coloring the disc and spinning it fast enough, our eyes cannotprocess

the colors fast enough and our brain therefore processes the color as an average of white

:Experimental method

:Newton’s disc

  • Cut paper into discs.
  • Divide disc into 6 or 12 equal parts.
  • Color each part in a different color by order: purple>blue>green>yellow >orange>red. Make sure the color is pale.
  • Insert toothpick into center and stabilize with plasticine.

:Color assembly

  • Cover each flashlight with one color of cellophane plastic.
  • Shine light on white wall or paper. See color of each light.
  • Shine different color lights in the same place simultaneously. See the colors that are created

List of equipment:

  • White paper circles
        • Colored pencils or crayons.
        • Toothpicks
        • Plasticine
        • Scissors
        • Ruler
        • Pure color cellophane plastic: red, blue and green.
        • Three white flashlights.
        • Rubberbands
