Question

(4) As given in the following table, a particular lens in some optical system is made of a wavelength-dependent glass. a) Plot the index of refraction as a function of wave- length. b) From the graph, what is the wavelength at the minimum and maximum index? c) Using linear regression, fit a line to the data of Table 1. d) Now, fit a power law to the data of Table 1. e) Is the line a better fit than a power law to the data? Why or why not? color wavelength (nm) index dark blue blue-green yellow red dark red 450 495 570 685 750 1.528 1.523 1.517 1.514 1.511
