SUMMARY

The discussion centers on solving a physics problem involving the spherical interface formula, specifically (n1/p) + (n2/q) = ((n2-n2)/R). A user calculated q to be 15 cm but could not reconcile this with the expected answer of 23 cm. Another participant suggested that the flat end of the rod must be considered in the calculations, indicating that the problem requires a more comprehensive approach to account for all geometrical factors involved.

PREREQUISITES
  • Understanding of spherical interface formulas in optics
  • Familiarity with the concepts of refraction and indices of refraction
  • Basic knowledge of geometry related to rods and flat surfaces
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Research the derivation and applications of the spherical interface formula in optics
  • Study the effects of flat surfaces on light refraction
  • Explore problem-solving techniques for complex physics problems
  • Review examples of similar physics problems involving rods and interfaces
USEFUL FOR

Students studying physics, educators teaching optics, and anyone interested in solving complex refraction problems.

Does anyone know how to solve this problem? I tried using the spherical interface formula (n1/p)+(n2/q)=((n2-n2)/R) and I get q=15cm which I cannot seem to relate to the answer provided (23cm). Anyone know the correct way to approach this problem?

You probably need to account for the flat end of the rod as well.
