O6: Refraction: ray diagrams and Snell’s Law Materials: Ray box, masking tape, semi-circular prism, rectangular prism, triangular prism, convex and concave lenses, polar graph paper Initial instructions and questions: 1) Take a semi-circular prism, and for various incident light rays, sketch the path of the light, and sketch in dotted lines where you would see the ray if you looked at the prism straight on. 2) Hold your rectangular prism at various angles to the incident light ray. Record the angle of incidence and the angle of refraction by making a table.

Unformatted text preview: (Remember that light travels in straight lines inside the prism, and that once it comes out, it has been refracted (bent) twice!) 3) For a triangular prism, make a prediction for where light will exit the prism. Draw a diagram. Obtain a triangular prism and try it. 4) Your instructors will show you two different lenses. Predict the path of the light through the lenses. Show your prediction to your instructors. They will give you some lenses and you can try it. Remove the tape from your ray box. Do the rays come together?...
