Spectra Interference: Crash Course Physics #40

Season 1 Episode 40 | 8m 21s

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.

Extras
Shini introduces the idea of Quantum Mechanics and how it helps us understand light.
Why is e=mc2 such a big deal? And what about this grumpy cat in a box and probability?
Let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it useful?
We've all heard of relativity, but what is it? How does it relate to light and motion?
Getting power at home is pretty amazing – and much more complicated than it may seem.
We've talked about how AC circuits change voltage, but let's take a deeper look.
Sunlight, moonlight, torchlight... They all work the same. Let's talk about light!
Light's behavior seems counterintuitive. That is, until you figure out light is a wave.
Maxwell's Equations tell us a lot about electromagnetic interactions and physics.
Shini talks to us about optical instruments and how they make magnification possible.
