Light Absorption and Color Perception

Becca Emmerich from Edmund Optics explains the concepts of light absorption and reflection, detailing why objects appear certain colors. The video demonstrates these concepts using filters and a flashlight, showing how different colors are absorbed or reflected. An experiment with gummy bears and lasers further illustrates light absorption. The video concludes with a reminder that the colors we see are due to the absorption and reflection of light, and encourages viewers to explore more at Edmund Scientific.

• The speed of light

• The structure of the eye

• Absorption and reflection of light
