Optical path difference caused by double slit

Click For Summary
SUMMARY

The discussion centers on the optical path difference caused by a thin glass covering S2 in a double slit experiment. When light passes through the thin glass, it undergoes refraction, which alters the path length of the light originating from S2. This change in optical path results in the observed movement of interference fringes toward point Y. The phenomenon is attributed solely to the effects of refraction as light transitions between different media.

PREREQUISITES
  • Understanding of the double slit experiment
  • Knowledge of light refraction principles
  • Familiarity with optical path length concepts
  • Basic physics of wave interference
NEXT STEPS
  • Study the principles of light refraction in different media
  • Explore the mathematical formulation of optical path length
  • Investigate the interference patterns produced in double slit experiments
  • Learn about the impact of various materials on light behavior
USEFUL FOR

Students of physics, educators teaching wave optics, and anyone interested in understanding the principles of light behavior in interference experiments.

What do you think might be going on here?
 
Only The light originate from s2 will pass thru the thin glass.

List the things you know happen when light passes from one medium through another.
 
Refraction happen

as i know , only refraction happen. after googling, i also get refraction happen.
