SUMMARY
The introduction of a convergent lens in Young's experiment alters the interference pattern by reducing its size when placed between the slits and the screen. Conversely, a diverging lens enlarges the pattern, especially when the screen is positioned beyond the focal point. The interference fringes are affected by the lens type and placement, with the rays from image points only crossing when the screen is located past the focal point of the lens.
PREREQUISITES
- Understanding of Young's double-slit experiment
