Unformatted text preview: cally dense (large n) medium. D) Total internal reflection can occur for light traveling either way across a boundary. E) For angles of incidence greater than the critical angle, all the light is absorbed in the second medium. 4. A beam of light travels from air into a sheet of glass having refractive index n. Which one of the following statements about this light is accurate? A) If we increase the angle of incidence, the angle of refraction decreases. B) If we increase n, the angle of incidence d...
