Question

0.82 pm. Compute the fractional bandwidth of a source at 0.82 um having the spectral width 1 nm and 20 nm. Compute the bandwidth in hertz. 3.7 Commute the reflectance at an AIG As.to.gir boundary at normal incidence Compute

Answer 1

3.6 Sol: Given central wavelength a=0.82 mm f: E= 3x108 33.6681014 0.82X166 fractional bandwidth is geven as: = 82- -0 faz Ç = 3x100 = 1.5x1016 20x10 = 3x108 = 3 X 10't f2 = Txeong - 30 X10 lo 16 fa upper J, ә Сәміл frequency ула ушла equation 0 in putting values Хи 23000X2014- 15081014 3.668 1019 Ans. = 778.69 HZ
