This handout as either a MS publisher file to edit or PDF to print helps students completing an experiment using a semi-circular prism and ray box to: Line up the prism correctly, Position the Ray Box to correctly aim the incident ray Measure both the incident ray and the refracted / reflected ray easily. Enjoy! (I welcome any constructive feedback)

A Handout with a protractor on the page to help students: Line up their semi-circular block correctly, Know where to aim their incident ray of light from their ray box and Measure the angle to the Normal for both refraction and total internal reflection Enjoy! (I welcome any constructive feedback)
