Today, Class, we are going to go over light:reflection and refraction
Does anyone know about reflection of light?
Light:Reflection and refraction
Like when light bounces off something, and causes us to see color? And all the other colors are absorbed
When all colors are reflected we see white and when all colors are absorded we see black.
Exactly. Everything we see, we see because our eyes filter out a certain group of electromagnetic waves called the visible spectrum.
I didn't know that.
That is why when there is no light at all, we can't see anything.
Does anyone know what it is called when light travels through a different mediums? Such as a thick gas or water?
This would explain what is going on when your body looks different under water while you are swimming, or a wavy figure in an oasis in the desert.
That must be refraction! Refraction is the reflection through 2 different densities
