LAB 22. Index of Refraction
Objectives: To determine the index of refraction of an acrylic block
Equipment: Optics bench, ray table, light source and acrylic block
Type of Lab: Open ended

LAB 23. Mirrors and Lenses
Objectives: This lab is divided into two sections:
1. Using a concave mirror, determine two locations where a magnified image can be formed.
2. Determine the focal length of a converging lens directly and the focal length of a diverging lens by combining it with a converging lens.
Equipment: Optics bench, set of lenses and mirrors, light source
Type of Lab: Open ended

LAB 24. Interference
Objectives: To determine the wavelength of a source of light by using a doubleslit and a diffraction grating of known spacing.
Equipment: HeNe Laser, slits and meterstick
Type of Lab: Open ended

KEY ITEMS:

• Students difficulties in geometric optics have to do with not having a clear
  idea of what  the ray model of light is and the role of the three principal rays.
• They also have problems understanding the two types of images: virtual and
  real. The best way to help them is by performing demos and/or experiments
  accompanied by graphical descriptions.
