Dear All, I am working on optical properties of perovskites. I have determined graphical behavior of refractive index, extinction coefficient, reflectivity, energy loss function as a function of frequency. when I move to absorption coefficient, it needs specific wavelength [image: extinction absorption coefficient equation]. Can anyone guide me in this path. I just want to know how to take the value of wavelength in the expression. Thanks in advance.
