Unformatted text preview: Reflection and Refraction at a Boundary - 7 Light of freespace wavelength 1 , 550 nm is widely used in fiber optic communica- tions. This light is inside a semiconductor material Ga . 7 Al . 3 As and is incident upon a planar interface with air. At 1 , 550 nm , the refractive index of Ga . 7 Al . 3 As is 3.2998. Both TE and TM polarizations are present in the incident light wave. For the above semiconductor/air interface, calculate, showing all work, the Brew- ster angle (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 an- swers in the spaces provided. The incident light has an angle of incidence is 15 ◦ 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,culate, showing all work, the quantities on the attached sheet....
