D= Diameter of the pulley. R = Radius of the experimental rod. G =Acceleration due to gravity. L1 – L2 = distance between two pointers. θ1– θ2 … Read more

## Determination of young’s modulus by flexural method.

Objective: To determination of Young’s modulus by flexural method. Theory: If a bar of breadth b and depth d is placed horizontally on two knife edges separated by a distance L, and a load of mass m, applied at the midpoint of the bar produces a depression x of the bar, then the Young’s modulus … Read more

## Dermine the wavelength of the incident light by Newton’s ring method

Objective: – To determine the wavelength of the incident light by Newton’s ring method.  Theory:- When a parallel beam of monochromatic light is incident normally on a combination of a plano-convex lens L and a glass plate P, as shown in the fig below, a part of each incident ray is reflected from the lower … Read more

## Determine the wavelength of unknown light by laser diffraction method

Objective: To Determine the wavelength of unknown light by laser diffraction method. Theory:  If a parallel beam of light of wavelength λ is coming out  from a diffraction grating,  placed  vertically  on  the   optical bench, then  the  diffracted rays  from  the  grating  will  form  at  the  focal plane, a  number  of  primary  maxima  of  different  order  numbers(n)  on  both  sides  … Read more
