Assume you have a somewhat idealized J-band system with spectral response of 0.8 from 1.15 through 1.35 mm and zero outside this range.

What is the effective (mean) wavelength?

Solutions

Expert Solution

What is the effective (mean) wavelength is given by

                                        lamdamean =1+(5/6)(Deltalamda/lamda2) +(deltalamda/lamda)4

                                                            =1+(0.833)(0.35/1.35mm2)+(0.35/1.35)4

                                                                                     = 1+0.833(2.592*10-4)+(4.426*10-3)

                                                           = 5.64*10-3m

                                                          =5.64mm
