Quantum Mechanics - Part 1: Crash Course Physics #43
What is light? That is something that has plagued scientists for centuries. It behaves light a wave... and a particle... what? Is it both? In this episode of Crash Course Physics, Shini introduces...
==========
Here’s a question that’s plagued physicists for centuries. What exactly is light? When we talked about this earlier, we came to the conclusion that light is a wave. Which it is. Or at least, light behaves like a wave, when you you use it in certain experiments. So for most of the 19th century, it seemed like the question had been settled. Physicists agreed: light is a wave. Then, new discoveries made them start to question that. They started getting more and more clues that light could also behave like a particle. Which led to the strange concept that light was both a particle and a wave. This kickstarted the development of a little something you might have heard of, called quantum mechanics.
