Michelson Interferometer question

Click For Summary
SUMMARY

The discussion focuses on calculating the intensity of light passing through a Michelson Interferometer with a beam splitter that transmits 1/3 and reflects 2/3 of the light. The initial intensity is denoted as I0. Participants are advised to trace both paths of the light, applying the respective transmission and reflection coefficients: multiply by 2/3 for reflections and by 1/3 for transmissions. This systematic approach leads to the final intensity calculation.

PREREQUISITES
  • Understanding of optical physics principles, specifically interference.
  • Familiarity with the Michelson Interferometer setup and its components.

Light can take one of two paths in a Michelson interferometer. Call the initial intensity I0, and trace both paths to see what the final intensity is. Every time the light reflects, multiply the original intensity by 2/3; every time it transmits, multiply the intensity by 1/3.
