4. Snell’s Law (page 13): Determine the index of refraction of acrylic by measuring
angles of incidence and refraction of a ray passing through the rhombus.
5. Total Internal Reflection (page 15): Determine the critical angle at which total
internal reflection occurs in the rhombus.
6. Convex and Concave Lenses (page 17): Use ray tracing to determine the focal
lengths of lenses.
7. Hollow Lens (page 19): Use the hollow lens and water to explore how the prop-
erties of a lens are related to its shape, its index of refraction, and the index of
refraction of the surrounding medium.
8. Lensmaker’s Equation (page 21): Determine the focal length of a concave lens
by measuring its radius of curvature.
9. Apparent Depth (page 23): Measure the apparent depth of the rhombus and
determine its index of refraction by comparing the apparent depth to the actual
thickness.
Optics Bench Experiments These experiments use the Optics Bench, Mounted
Lenses, and Viewing Screen. Experiments 10 and 13 also use the Light Source.
10. Focal Length and Magnification of a Thin Lens (page 27): Determine the
focal length of a converging lens by forming an image on the viewing screen.
11. Telescope (page 31): Construct a telescope and determine its magnification.
12. Microscope (page 35): Construct a microscope and determine its magnification.
13. Shadows (page 39): Show the umbra and the penumbra of a shadow.
