- Shine coherent light onto a spherical object and a dim spot of light appears in the center of the object’s circular shadow. This spot is called a Poisson spot, or Arago spot, and can be explained using the wave interpretation of light.
- Green or red lasers, diverting lens, optics track and components located in L35, section A. BB in glass slides located in L01, section B6.
- Interference fringes result when two plates of glass are
separated by a thin wedge of air.
- Located in L01, section B5.
- Glass plates coated with different thicknesses of dielectric
material transmit and reflect different wavelengths of light.
