Product Description

He-Ne LASER KIT

Experiment

Exp-1 To demonstrate that light spreads when it passes through a narrow aperture.
Exp-2 To observe the diffraction patterns by holes, single slit and double slit, mesh, grating.
Exp-3 To demonstrate Young's fringes.
Exp-4 To demonstrate Fresnel's diffraction.
Exp-5 To measure wavelength of light using a millimeter scale as a grating.
Exp-6 To demonstrate fringes of equal inclination

Principle and Working :
Diffraction phenomenon of light cab be observed when a laser beam passes through a slit or grating. The diffraction pattern can be observed on a translucent screen.
In the present setup single slit, double slit, multiple slit, single tapered slit, fine grating, holes, circular opaque spot, gray filter, mesh and coarse grating are used for diffraction experiment with a he-ne laser.
