Determination of Young’s Modulus Using Cornu’s Method
Equipment Used
Six-Position Travelling Microscope – This device is used to carefully observe and measure the movement of interference fringes during the experiment.
Sodium Lamp Assembly – It provides a single-color light source, which is essential for creating clear and well-defined interference patterns.
Sample Glass Plate with Plano-Convex Lens – This setup is used to create the necessary optical configuration for observing the interference effects and analyzing the material’s elastic behavior.
Slotted Weights Set – These weights are used to apply a controlled amount of force to the sample, allowing for the measurement of its deformation and the calculation of Young’s modulus.
This experimental arrangement allows for the precise calculation of Young’s modulus and other elastic properties of transparent materials using optical interference techniques based on Cornu’s method.
