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 higher energy level to a 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. -

Beer Lambert’s Law Experiment
Objectives:
To find the concentration of a liquid using the samples of known concentration using the Beer lambert’s Law.
Principle:
Beer Lambert 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.
Key Features:
• Precise Optical Alignment: The optical alignment of the components is attained by optical bench, the setting up time is faster and
experimentation is easy.
• Digital Lux Meter: This enables measurement of light intensity at various angles of reflection. The meter reads with a precision of 1 lux.What You Need

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 straight conductor and different types of circular coils. -

Energy Band Gap Experiment
Objectives:
To find the energy band gaps for different semiconductor diodes and LEDs
Principle:
At absolute zero-degree temperature, semiconductors are pure insulators. As the temperature is increased thermal energy create vibrations in crystal lattice and few electrons, which acquire sufficient vibrational energy break their covalent bond, become free, and move to the conduction band. The energy required to rapture the covalent bond is designated as energy gap EG and termed as energy gap or band gap energy.
Key Features:
• Built-In Heater: The heating element is built in the system and is powered by 12V input. The efficient heating mechanism heats the system to required temperature in a few minutes with minimum power requirement of 40W.
• Modular Design: The modular design of the setup allows testing of multiple diodes as well as different LED’s.
• Built-In Voltage and Temperature Probe: All the necessary parameters to be measured are available directly on the setup itself.- Product code is EBG1-C

Faraday Effect Experiment
OBJECTIVES:
- Observe the effect of a magnetic field on plane of polarization of polarized light as it passes through a dispersive medium
- Measure the Verdet’s constant of a given dispersive material.
PRINCIPLE
When a linearly polarized light passes through an optical medium in a region of 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 optical medium and component of magnetic field in the direction of light. The factor of proportionality is a 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 SF6 glass cube. -
