Experiment
Atomic Spectra Experiment
OBJECTIVES
- To understand the concept of diffraction of light.
- To measure and analyze the emission spectral lines of different elements.
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.

Experiment
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.BAE1-C -
Experiment
BH Curve Experiment
Objectives
To observe and study the magnetization behaviour of the ferromagnetic magnetic materials provided.
Principle
The B-H curve is the curve characteristic of the magnetic properties of a material or element or alloy. It tells you how the material responds to an external magnetic field, and is a critical piece of information when designing magnetic circuits. A Ferromagnetic material, retains its magnetization even after the external magnetic field is removed. And the reversal or change in the direction of the applied external magnetic field results in a change in the magnetization of the ferromagnetic material. It is seen that the change in the magnetization lags behind the change in the applied external magnetic field. Thereby, a hysteresis behaviour is exhibited.
Key Features
- Compact Setup – The apparatus design is compact and yet effective to perform the experiments with ease. The simple connections and stand to hold the teslameter probe, makes it easy to handle.
- Multiple samples included – Multiple ferromagnetic samples are provided to study the BH curves of the different materials. The removable cores make it easy to change between samples.

Experiment
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 -
