Unformatted text preview: Reflection and Refraction at a Boundary - 6 Light of freespace wavelength 435 . 8 nm is widely used in photolithography. This corresponds to the g line of a mercury discharge lamp. This light is incident in air upon a planar interface with BK-7 glass. Both TE and TM polarizations are present in the incident light wave. For the above BK-7/air interface, calculate, showing all work, the Brewster an- gle (if it exists) and the critical angle (if it exists). For these calculations, use 1 . 000 for the refractive index of air. Express angles (if they exist) in degrees accurately to within 0.0001 ◦ . If an angle does not exist, write “does not exist.” Put your final answers in the spaces provided. The incident light has an angle of incidence is 65 ◦ as measured counter-clockwise from the normal. For this case, for the reflected and transmitted propagating waves, cal- culate, showing all work, the quantities on the attached sheet. For these calculations, use 1 . 000 for the refractive index of air. Express angles in degrees accurately to within 0.0001 ◦ . Express fractions accurately to within 0.00001. Write your final answers in the spaces provided. Brewster angle (if it exists) = ◦ Critical angle (if it exists) = ◦ TE Polarized Transmitted Wave Angle of transmitted wavevector (with respect to normal to boundary) = ◦ Fraction of amplitude transmitted = Phase shift upon transmission = ◦ Fraction of power transmitted = TE Polarized Reflected Wave Angle of reflected wavevector (with respect to normal to boundary) =...
