Principle

Visible light impinges on a diffusely reflecting surface. The luminance of this surface is determined as a function of the angle of observation.

Benefits

  • study the light intensity that a sheet of paper is diffusely reflecting
  • learn about the different physical units associated with light
  • very versatile optical base plate

Tasks

  1. The luminous flux emitted reflected by a diffusely reflecting surface is to be determined as a function of the angle of observation.
  2. Lambert's law (cos-law) is to be verified using the graph of the measurement values.
