Unformatted text preview: Reﬂection and Refraction at a Boundary  1 Light of freespace wavelength 546.1 nm (e line) is incident in air upon a planar
surface of BK7 glass. The angle of incidence is 60° measured counterclockwise from the normal. Both TE and TM polarizations are present in the incident light wave. For the transmitted and reﬂected waves7 calculate, showing all work, the quanti—
ties on the attached sheet. Express angles in degrees accurately to within 0.0001°. Ex— press fractions accurately to within 0.00001. Write your ﬁnal answers in the spaces pro— vided. TE Polarized Transmitted Wave Angle of transmitted wavevector
