Determination of Hall effect of a known Semiconductor

The apparatus list included electron gun, Helmholtz coil, e/m tube or glass tube filled with helium gas, voltmeter, ammeter

Spectrometer is used to conduct spectrum related optics experiment. It is useful for many experiments

Determination of Stefan's Radiation constant using a vacuum tube diode.

Laser diffraction method to find out the wavelength of light

In this video you can find the procedure , data table along with graph and calculation of Modulus of Rigidity of the wire of the material (aluminium). watch it carefully and try to understand.

In this experiment we will use specific gravity bottle to measure the weight of sand and the reference substance that is water. then using formula of Relative density we will reach our conclusion.

In this video you can learn to take reading from vertical or horizontal scale of Traveling microscope. first you need to determine the vernier constant of traveling microscope then linear scale reading and Vernier scale reading.

There are two steps in this experiment first part is to calculate pitch and least count of Spherometer second part is to find out l and h l is the average distance between three legs of Spherometer and h is the thickness of convex lens to be measured using Spherometer hence using the formula of radius of curvature R= (l²/6h ) h/2 we can easily calculate R

we are taking temperature verses voltage reading while current is fixed (I=5mA) and calculating resistivity , using four probe method .Then plotting a graph ,temp inverse verses log of resistivity. lastly using working formula calculating Energy gap or Band gap.

Apparatus used - spectrometer ,helium source discharge tube , traingular prism of made crown glass and table lamp

In this video we are going to conduct Newton s ring experiment. The inference pattern dark or bright fringes appeared here and it was firstly observed by Sir Isaac Newton in 1917. That's why the rings named after his name.

In this video we will conduct the experiment to find unknown resistance with help of Carey Foster's bridge. Carey Foster's bridge is little more advanced than wheatstone bridge ,invented by scientist Carey Foster . The main working principle is same as wheatstone bridge principal. we first will find specific resistance of bridge wire then will find the unknown resistance.
