Crash Course Physics #40: Spectra, Interference, and Polarization

Curated by ACT

This video episode of Crash Course Physics focuses on what we can learn from light. Light is everywhere but it's not as predictable as you might think. It's a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time! We've learned how to bend light to our will, with lenses and mirrors, but it's time to take a step back and ask what we can LEARN from light. [8:25]
