Lab: Reflection and Refraction Post-‐Lab Knowledge Check PHYS 242
Post-‐Lab Knowledge Check A. Suppose you shine a laser pointer from air (with n = 1) to
diamond (with n = 2.419) at an incident angle of 10°. Draw the resulting path of the beam as it travels from air to diamond. Calculate the angles using Snell’s Law.
B. Suppose you shine a laser pointer from air (with n = 1) to diamond (with n = 2.419) at an incident angle of 60°. Draw the resulting path of the beam as it travels from air to diamond. Calculate the angles using Snell’s Law. How does your result compare with Part A? Explain.
