Diode Laser Diffraction: This Experiment setup is used to study the diffraction phenomenon of light which can be observed when a laser beam passes through a diffraction slit. The intensity pattern can be determined using a pin photo detector with fine movement across the diffraction pattern.






Electrical Conductivity Of Metal: The electrical conductivity of a metal (Copper & Aluminum) is determined by the resistance R of the rod and its geometric dimensions (l=0.315 m, A = 4.91 x10-4 m2).







Field Lines & Equipotential Lines: This Experiment setup is used to study the diffraction phenomenon of light which can be observed when a laser beam passes through a diffraction slit. The intensity pattern can be determined using a pin photo detector with fine movement across the diffraction pattern. In the present setup, the light intensity in the terms of current or voltage is noted at closed intervals by finely traversing the detector movement and observing the light intensity on a digital multimeter.

Balmer Series And Rydberg Constant: In this experiment set-up a discharge lamp is used to emit hydrogen atoms which form a series of lines in the visible part of the spectrum.

BH Curve Loop/ Magnetic Hysteresis Loop Tracer: In this experiment when a cylindrical sample is placed coaxially in a periodically varying magnetic field the magnetization in the sample also undergoes periodic variation.

Dielectric ConstantThe main objective of this experiment is to verify the relation between capacitance C, charge Q and charging voltage E which is given as C=Q/E. The capacitance of a parallel plate capacitor depends upon the distance d between the plates, area A of the plates and the nonconductive material (having dielectric constant) between the plates.
