How do we really know what's out there?

How do we really know what's out there?. Space is a pretty big place and, after all, we've never been farther from earth than our moon. How do we know what the stars are made of?. This is the electromagnetic spectrum . It consists of waves which vary in

Wave Interactions

Wave Interactions. Reflection. The bouncing back of a wave when it meets a surface or boundary. Diffraction. The bending of a wave as it passes an edge or an opening. This is why you can hear sound around a corner. Refraction. The bending of waves as they pass from one medium to another.
