WAVE OPTICS

Objective: Demonstrate the wave nature of light and determine the wavelength Diffraction of light by a single slit can be described as the superposition of coherent wavelets which, according to Huygens’ principle, spread out from the illuminated ... more

Objective: Demonstrate the wave nature of light and determine the wavelength.The diffraction of light by multiple slits or a grating can be described by considering how the individual components of the coherent wave radiation are superimposed ... more

Objective: Generating interference between two beams using a Fresnel biprism. Refraction of a divergent light beam by means of a biprism separates the beam into two parts which, since they are coherent, will interfere with one another. The ... more

Objective: Observe Newton’s rings in monochromatic light Newton’s rings are generated by a set-up involving a flat glass plate and a spherical body with a large radius of curvature. If parallel monochromatic light is incident on the set ... more

Objective: Demonstrate and investigate how a Michelson interferometer works In a Michelson interferometer a coherent light beam is separated into two rays travelling in different directions by inserting a half-silvered mirror in the path ... more

Objective: Determine the refractive index of glass A Michelson interferometer can be used for interferometric measurement of refractive indices in particular because it is sensitive to changes in the optical path of a split beam of light ... more

Objective: Demonstration of “quantum erasure” in an experiment by analogy Light itself can be described in quantum mechanics by means of wave equations. From this it is possible to derive the spatial distribution of the probability density ... more
