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…
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…

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,…

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…
OBJECTIVES To experimentally verify the malus’s law. PRINCIPLE Light, when modelled 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,…
Objectives To study the photoconductivity of CdS Photoresistor, in the following conditions: Applied voltage vs photocurrent (IPH) at constant irradiance (Φ). Photocurrent (IPH) vs irradiance (Φ) at constant applied voltage (V). Principle The phenomenon of photoconductivity occurs when an incident light shown upon a semiconductor causes an increase in its electrical conductivity. This is because of excitation of electrons across…

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…
Objectives: To study the effect of wave plates on polarized light • Quarter wave plate • Half wave plate Principle: Waveplates are optical devices that resolves a light wave into two orthogonal linear polarization components by producing a phase shift between them. The transmitted light may have a different type of polarization than the incident beam due to the induced…

Objectives: • To find wavelength of given laser using the slit of known width. • To find the slit width knowing the wavelength of light used. • Proving the concept of Heisenberg uncertainty principle. Principle: Diffraction is a phenomenon of bending of waves when it encounters obstacles or narrow opening. A basic set up to observe diffraction consists a laser,…
OBJECTIVES To measure the width/thickness of the given samples by analyzing the diffraction pattern. PRINCIPLE The characteristics of light such as interference, diffraction can be understood when light is studied as a wave phenomenon. Interaction of waves with matter results in either transmission, reflection, absorption and diffraction of the wave. When the size of matter is comparable to the wavelength…
