1. Draw the reflectance and transmittance as a function of incident angle for air and SF10 glass interface at 550 nm under external and internal reflection condition, respectively. (Note: read refractive indices from the curves below and calculate the reflectance and transmittance for both TE and TM modes.) 1.9 Lanthanum dense flint LaSF9 1.8 Dense flint SF10 1.7 Refractive index n Flint F2 1.6 Barium crown BaK4 Borosilicate crown BK7 1.5 Fluorite crown FK51A 1.4 - 0.2 . 1 1.0 1 1.4 0.4 0.6 0.8 1.2 1.6 Wavelength a (um)
