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 ...

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 ...

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 ...

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 ...

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 ...
