Crash Course Physics
Spectra Interference: Crash Course Physics #40
Season 1
Episode 40
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.

Let's talk about astrophysics, cosmology and how our universe works.
10:19
Let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it useful?
9:02
Why is e=mc2 such a big deal? And what about this grumpy cat in a box and probability?
8:38
Shini introduces the idea of Quantum Mechanics and how it helps us understand light.
8:25
We've all heard of relativity, but what is it? How does it relate to light and motion?
9:56
Shini talks to us about optical instruments and how they make magnification possible.
9:41
Light's behavior seems counterintuitive. That is, until you figure out light is a wave.
9:26
Sunlight, moonlight, torchlight... They all work the same. Let's talk about light!
Maxwell's Equations tell us a lot about electromagnetic interactions and physics.
9:53
We've talked about how AC circuits change voltage, but let's take a deeper look.
8:18
Getting power at home is pretty amazing – and much more complicated than it may seem.
9:03
Megneto helps Shini explain how induction works and why magnetism seems so complicated.
