Question
What is intensity (or) amplitude division?
Advertisements
Solution
- If we allow light to pass through a partially silvered mirror (beam splitter), both reflection and refraction take place simultaneously.
- As the two light beams are obtained from the same light source, the two divided light beams will be coherent beams.
- They will be either in-phase or at constant phase differences.
- Instruments like Michelson’s interferometer, FabrayPerrot etalon work on this principle.
