Special thanks to my friend Judith who sent me this picture.

Green Laser Reflection and Refraction

 

Anytime you observe reflection and refraction, you get actually multiple reflections and refractions.  Any reflected or refracted ray becomes an incident ray and is once again reflected or refracted at the boundary.  The useful skill is then to recognize which ray is which one and select only the those needed for the experimet.

Laser ray captured between two glass surfaces

 Photo 1. The laser ray is captured between two glass surfaces.  

 Picture 2.  The incident, reflected, and refracted rays are sketched.  Notice that the two refracted rays at the left are parallel (the same angle of refraction!)

Picture 3.  White A at the right side indicated an incident angle; the blue A shows a reflected one. All angles A are equal.  B in lower right corner is an angle of refraction, other B-angles are both incident and reflection angles. All angles B are equal.
