DIODE LASER KIT
DescriptionExp-1 To demonstrate Young’s fringes.
Exp-2 To demonstrate diffraction pattern by pinhole, single slit, double slit & grating.
Exp-3 To demonstrate Fresnel’s diffraction.
Exp-4 To determine the slit or pinhole width.
Exp-5 Light spreads when passed through a narrow aperture.
Exp-6 To measure wavelength using a millimeter scale as a grating..
Principle and Working :
Diffraction phenomenon of light can 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, a 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 diode laser.
