Atomic Spectra Experiment
OBJECTIVES
PRINCIPLE
The source of electromagnetic radiation is atoms. When the atoms of an element are in an excited state, they return to a lower energy state by emitting electromagnetic (EM) radiation. The transition of the electrons in the atom from a higher energy level to lower unique energy levels for the occupation of electrons, due to this the EM spectrum emitted is a unique signature of an element or a substance. The study of the characteristics of EM radiation emitted by atoms is called Atomic Emission Spectroscopy.

Brewster Angle Experiment
OBJECTIVES
Measurement of Brewster’s angle for a given dielectric dispersive medium.
PRINCIPLE
When un-polarized light is incident on the surface of a dielectric (such as a glass), at a certain angle of incidence the reflected light is completely plane-polarized. This phenomenon was discovered by Sir David Brewster and, thus, the specific angle is called Brewster’s angle or polarization angle. Also, from the experiment, it can be confirmed that the reflected ray and the refracted ray are 90° apart when the incident angle is set at Brewster’s angle.

Biot-Savart’s Law Experiment
OBJECTIVES
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.

Faraday Effect Experiment
OBJECTIVES
PRINCIPLE
When linearly polarized light passes through an optical medium in a region of the strong magnetic field, the plane of polarization of linearly polarized light rotates by an angle. The angle of rotation of plane-polarized light is proportional to the length of the optical medium and component of the magnetic field in the direction of light. The factor of proportionality is medium-specific and is called Verdet’s constant and this effect is known as the Faraday Rotation or Faraday Effect. Discovered by Michael Faraday in 1845, the Faraday effect was the first experimental evidence that light and electromagnetism are related. In the experimental setup, the optical medium is an SF6 glass cube.

Malus Law Experiment
OBJECTIVES
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.
