Product Specification Product DescriptionExperiments:

• Exp-1 To measure the thickness of glass slide.
• Exp-2 To study the Mach-Zender.
• Exp-3 To study two-beam interferences.

Principle and Working:The Mach-Zender interferometer consists of two semi-reflecting plates (beamsplitters) and wo mirrors. A light beam is divided into two, after which both beams are recombined by eans of a semi- reflecting mirror. One of these beams will be named the Reference beam, while the other will allow us to take measurements on the vacuum index or plate thickness.

Product Specification Product DescriptionExperiments :

• 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 quarter wave plate.
• Exp-3 To study the polarization of light by two quarter wave plate.
• Exp-4 To verify the inverse square law.
• Exp-5 To verify Malus-law.

Salient features :

• Halogen light source.
• Computer connectivity.
• Precise measurement using vernier light sensor.

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, halogen light source with yellow light filter passes through a polarizer to produce linear polarized light. This polarized light then falls on a quarter wave plate λ/4. The emergent light passes through analyser. It is investigated at different angles of λ/4 plate ( 0°, 30°, 45°, 60° and 90°) between the optic axis of the wave plate and the direction of the incident light. The light intensity can be investigated with the analyser over the range -90° to +90°. At 0° and 90° of λ/4 with respect to optic axis, the transmitted light is linearly polarized, at 45° it is circularly polarized, and at 30° and 60° it is elliptically polarized.

Product Specification Product DescriptionExperiment :

• Exp-1 To demonstrate the kerr effect in nitrobenzene solution (only observation).
• Exp-2 To measure the light intensity as a function of voltage across the kerr cell using photo detector.

Salient Features :

• All electrical connections are made using safety sockets.
• Easy to setup experiment.
• Can be performed by diode laser and halogen lamp.

Principle and Working :
Certain materials under the influence of strong electric field become doubly refractive. The effect known as Kerr effect can be observed in this experiment with nitrobenzene solution.

In the present setup, a small glass container mounted with plate capacitor is filled with liquid. The container is kept between two filters placed at 90°. There will be dark field of view on screen initially but after applying electric field, the field of view brightens, because the light beam becomes elliptically polarised when passed through the birefringent liquid.
