SUMMARY

The equation 2t=mλ is used to describe the conditions for dark fringes in interference patterns. In this context, 'r' refers to the radius of curvature of the lens system, specifically a plano-convex lens, which is not to be confused with the radius of the dark fringe (r5001 dark). The value of r is critical for determining the spacing and position of the dark fringes in the interference pattern. Understanding the relationship between t, m, and λ is essential for accurate calculations in optical physics.

PREREQUISITES
  • Understanding of wave interference principles
  • Familiarity with plano-convex lens properties
  • Knowledge of optical path length calculations
  • Basic skills in solving equations involving multiple variables
NEXT STEPS
  • Research the properties of plano-convex lenses and their applications in optics
  • Study the concept of dark fringes in wave interference and how to calculate them
  • Learn about the significance of the wavelength (λ) in optical experiments
  • Explore advanced topics in optical path length and its impact on interference patterns
USEFUL FOR

Students studying optics, physics educators, and anyone involved in experimental physics focusing on wave interference and lens systems.

how can i calculate r5001 dark,also ,what is the meaning of r in qusetion(r=5mm),<----- it is not the curvature R of plano-convex lens also it is not r5001 dark,since it will get incorrect answer so what is radius r mean?
