Malus's Law Apparatus
Malus's Law Apparatus
Malus's Law Apparatus dedicated to elucidate students to understand the wave nature of light. LED is used as a source of unpolarized light. With the help of this apparatus the basic law of polarization, Brewster's law, and Malus law experiment can be verified. Polarization can be studied by direct vision as well as by reading the variation of intensity through a digital ammeter connected across a photodetector. The verification of Malus law experiment can be done in two different ways using two coaxial polarized and a combination of a glass plate and Polaroid. All the above experiments can also be performed using an unpolarized laser as the source of light.
Scope of Learning
1. Study of Polarization of light by reflection and thus verify Brewster's law.
2. Study and verify Malus's law using a plain glass plate and a Polaroid by Malus's Law Apparatus.
3. Study and verify Malus's law using two Polaroids.
4. To verify inverse square law.
