In this video we are going to look at how light and sound waves behave.
c = 299,792,458 m/s
Option: the Space-Time concept in Special Relativity
Light goes so fast that it broke our classical understanding of how speed works. We can fix our understanding with a little relativity and a space-time diagram, but you have to let go of any preconceived notions you might have about motion.
Light travel in straight lines.
