Additional Info

• ID Code: M7-14
• Purpose: Demonstrate polarization by reflection.
• Description:

  This gizzit contains a series of glass plates mounted at the Brewster angle, about 57 degrees. Unpolarized light entering one end confronts a series of surfaces, each of which reflects a fraction of the incident light which is polarized perpendicular to plane of the incident and reflected rays. After several such reflections the light exiting the other end is polarized in the plane of the incident and reflected rays (well, almost polarized).

  A bright light can be directed through this device onto a screen for group viewing.
