Reflection and Refraction of Light24322.16The angle of incidence is 112.00 mtan26.64.00 mθ−==°Therefore, Snell’s law gives ()111221sinsin1.333 sin26.6sin1.00nn−−=°36.6°and the angle the refracted ray makes with the surface is 290.090.036.653.4φθ=°−−°= °22.17The incident light reaches the left-hand mirror at distance ( )1.00 m tan5.000.087 5 m°=(above its bottom edge.
