Exp-1 To measure the light intensity of plane polarised light as a function of the analyzer position.
Exp-2 To study the polarization of light by half wave plate.
Exp-3 To verify the inverse square law.
Exp-4 To verify Malus-law.
Principle and Working :
A wave plate or retarder is an optical device that alters the polarization state of a light beam traveling through it. In the present setup, the diode laser light passes through polarizer to produce linearly polarized light. It then passes through the half wave plate L/2. The L/2 plate produces linear polarised light. For different angles of the L/2 plate with respect to optic axis only the polarisation plane changes. The maximum and minimum are not changed which can be investigated with the analyser over the range -90 to +90 degrees.
