The Michelson Interferometer - Indian Institute of ...
physics.iitm.ac.inThe Michelson interferometer is a device that produces interference between two beams of light. A diagram of the apparatus is shown in Fig. 1. The basic operation of the interferometer is as follows. Light from a light source is split into two parts. One part of the light travels

www.physics.utoronto.caA beam splitter is nothing more than a plate of glass, which is made partially reflective: as such, the splitting occurs because part of the light is reflected off of the surface, ... the whole field of view filled with light. ... point of zero path difference is reached, and then shrinking again, as that point is passed.
2.2 The Michelson-Morley Experiment
faculty.etsu.eduJun 24, 2019 · Example (Exercise 2.2.2). Suppose L1 is the length of arm #1 and L2 is the length of arm#2. The speed of a photon (relative to the source) on the trip “over” to the mirror is c − v and so takes a time of L1/(c − v). On the return trip, the photon has speed of c +v and so takes a time of L1/(c +v). Therefore the round trip time is t1 ...

www2.chemistry.msu.eduThe Michelson interferometer comprises a beam splitter, moving mirror, and fixed mirror. The light beam split into two by the beam splitter is reflected from the moving mirror and fixed mirror, before being recombined by the beam splitter. As the moving mirror makes reciprocating

(Next class period). b)The laws of E&M appeared ‘special’ in that their form changed depending on the state of motion of the observer (hwk 4c). c)Theory of heat failed to predict the energy emitted by a blackbody.

web.sbu.edu5 B. Special Relativity 1. Michelson-Morley a. Wave speeds Midway through the 19th century, it was established that light is an electromagnetic (E-M) wave. Maxwell showed that these waves propagate through the vacuum with a speed c ≈3x108 m/sec. Now, wave motion was well understood, so it was expected that light waves would behave
