Problem 4(14 points) Fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). White light falls normally on a transmission grating that contains N = 1257 lines. The grating has a width w=0.0368 m. a) [1 point] Which formula can be used to calculate the separation distance d between successive slits on the grating? (refer to the formula sheet and select the number of the correct formula from the list) b) [5 points] Calculate d. d= m c) [5 points] Assume d = 1.95-10-5 m; at what angle e in degrees will red light (1. = 6.35.10-7m) emerge in the first-order spectrum? (do not consider the small angle approximation) O= d) [3 points] Calculate the wavelength of this red light ( 10=6.35.10-7m), in a material where the index of refraction is 1.69. = m
