Without using the small angle approximation, what is the distance between the 1st dark fringe, and the 3rd non-central bright fringe (on the same side of the central maximum) on a screen 60 cm away from the double slit? (c) You are tasked with designing an experiment that has a tolerance for a maximum error of 5% in the wavelength. Can you use the small angle approximation with this physical setup? Explain by finding the percent error in the wavelength introduced if you solve part (a) using the small angle approximation
