Ok kids, so today we will be learning about Reflection, Refraction, and Diffraction.
What does all that stuff "mean" exactly?
Great question! So, Reflection is when there is a change in direction of waves when they bounce off a surface ( the waves bounce off a surface) Refraction is when there is a change in the direction of waves as they pass from one medium to another ( the waves pass through the surface)
Oh I almost forgot Diffraction. Diffraction is when a change in the direction of waves passes through an opening or around the surface, which was in their path ( the waves go through or around the surface) Rainbows are caused by diffraction as well if you didn't know...
