Malus Law Experiment
OBJECTIVES
- To experimentally verify malus’s law.
PRINCIPLE
Light, when modeled as a wave phenomenon, can be classified as a transverse electromagnetic wave consisting of oscillating electric and magnetic fields that are oriented perpendicular to each other. Depending on the orientation of the plane of polarization of the electric field with respect to the direction of propagation of the wave, the wave can be classified as polarized or un-polarized. To measure the variation of transmission of an EM wave through two polarizers as a function of the angle of orientation between them and prove Malus’s Law.

Interferometer Experiment
Objectives
- To produce and observe the interference pattern.
- To measure the wavelength of laser source using the interferometer.
Principle
Phenomena of interference can be explained by the principle of superposition. Consider two E.M waves simultaneously propagating through the same region of space. The resultant electric field at any point in that region of space is the vector sum of the electric field of each wave. Depending on the strength of the resulting electric field at a point in space where the two waves superpose, we observe dark and bright regions in the interference pattern.
Key Features
- Easy to Setup – The apparatus is built on a sturdy and portable platform. The legs are height adjustable to aid leveling of the platform & precise optical alignment of the laser beam. All this reduces the time taken for setup and aids the ease of measurements.
- High quality beam splitter and reflective mirrors – The setup comes with 40 x 40 x 40mm beam splitter cube and 40 x 40mm (98% highly reflective) mirrors for clear fringe pattern.
- 1 micron step movement – The complex double lever mechanism enables a least count of 1 micron in movement of the fixed mirror. Measurement error is less than 5% in wavelength measurement.

Size of Particle Experiment
OBJECTIVES
- To measure the width/thickness of the given samples by analyzing the diffraction pattern.
PRINCIPLE
The characteristics of light such as interference and diffraction can be understood when light is studied as a wave phenomenon. Interaction of waves with matter results in either transmission, reflection, absorption, or diffraction of the wave. When the size of the matter is comparable to the wavelength of the wave that it interacts with, a phenomenon called diffraction occurs. Diffraction of light due to particles is a function of the size of the particle and the wavelength of the light incident. It is possible to measure the size of a particle by studying the diffraction patterns created by it.SOP1-C -

Beer Lambert’s Law Experiment
OBJECTIVES
- To find the concentration of a liquid using the samples of known concentration using Beer lambert’s Law.
PRINCIPLE
Beer Lambert’s law relates the attenuation of light through a substance and the properties of that substance. Light interacts with matter in the following ways: emission, absorption, transmission, and reflection or scattering. Depending on the physical and chemical properties of the matter under interaction, there can be one or more ways in which light interacts. It is because of these interactions light can be used as a probe to measure the physical and chemical properties of materials.BLL1-C -

Experiment
Biot-Savart’s Law Experiment
OBJECTIVES
- Measuring the magnetic field of a straight conductor and of circular conductor loops as a function of the current.
- Measuring the magnetic field of a straight conductor as a function of the distance from the axis of the conductor.
- Measuring the magnetic field of circular conductor loops as a function of the loop radius and the distance from the loop.
PRINCIPLE
Electric currents generate magnetic fields. Biot–Savart law is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. In this experiment, we study the magnetic field characteristics in the straight conductors and different types of circular coils.BSL1-C
