Geometric Optics: Crash Course Physics #38

Season 1 Episode 38 | 9m 26s

Sunlight, moonlight, torchlight, and flashlight... They all come from different places, but they’re the very same thing: light! It’s what makes it possible for us to see the world around us, so it’s worth a close, hard look. For instance, how does light travel? When you flip that switch in the bathroom to brush your teeth, how does light move from the light bulb, to the mirror, and into your eyes?

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.
Light's behavior seems counterintuitive. That is, until you figure out light is a wave.
We've learned about light and how to bend it to our will. But what can we LEARN from it?
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.
