Indices of refraction when wavelengths are given

Click For Summary
SUMMARY

The discussion focuses on calculating the angles at which two wavelengths of light, λ1= 400 nm and λ2= 650 nm, exit a silicate flint glass prism. The relevant equation used is nair ⋅ sinθ1 = nprism ⋅ sinθ2, which relates the indices of refraction to the angles of incidence and refraction. Participants emphasize the need to determine the specific indices of refraction for the prism at the given wavelengths, suggesting the use of online resources for accurate data. The refractive index information can be found at the provided link to a reputable database.

PREREQUISITES
  • Understanding of Snell's Law and its application in optics
  • Familiarity with the concept of indices of refraction
  • Basic knowledge of light wavelengths and their properties
  • Ability to perform calculations involving trigonometric functions
NEXT STEPS
  • Research the refractive indices of silicate flint glass for various wavelengths
  • Learn how to apply Snell's Law in multi-wavelength scenarios
  • Explore the effects of angle of incidence on light refraction in prisms
  • Investigate the use of online databases for optical properties of materials
USEFUL FOR

Students studying optics, physics educators, and professionals in optical engineering who require a deeper understanding of light behavior in prisms and the calculation of angles based on varying wavelengths.

Homework Statement


A parallel beam of light containing two wavelengths, λ1= 400 nm and λ2= 650 nm, enters the silicate flint glass (at a angle of 41 degrees, relative to normal) of an equilateral triangle (60 degrees at each angle) prism. At what angle, relative to the normal, does each beam leave the prism.

Homework Equations


nair ⋅ sinθ1 = nprism ⋅ sinθ2

The Attempt at a Solution



I don't get how to get the two different indices of refraction for the prism, one for each given wavelength.

If not given, I would look them up on the internet.
