Unit 15: Waves and Optics – Geometric Optics

Snowflakes are beautiful. Light enters them and refracts (bends), separating the sun’s visible “white” light spectrum into rainbows of colors, while the snowflake also reflects glints of light twinkling back into our eyes. We will explore refraction of light through human-manufactured devices called lenses, and we will also take a look at reflection of light from mirrors.

This is a snowflake. No, really. It’s a snowflake! Click the picture to find out more.
