Covers the basics of light refraction, including density, refractive index, and the variation with wavelength.
Explores curvature, inflection points, and angular functions in plane curves, highlighting the importance of inflection points.
Explores refraction in a glass sphere scenario, explaining the discrepancy in perceived and actual distances of objects due to refractive indices.
Introduces hyperbolic geometry, covering complete metric spaces, isometries, and Gaussian curvature in dimension 2.
Explores dispersion in anisotropic media, covering k surface, uniaxial crystals, double refraction, beam walk-off, and applications of birefringent crystals.
