In a Young's double-slit experiment, blue light (?λ = 440 m) gives a second-order bright fringe at a certain location on a flat screen. What wavelength of visible light would produce a dark fringe at the same location? Assume that the range of visible wavelengths extends from 380 to 750 nm.
Calculate the wavelength that fulfills the problem description. Clearly show all steps, starting from generalized equations. Explain your mathematical work in words. Your explanation should cover both what you did, any approximations you make and the thought process behind why you did that.
Evaluate your answer to determine whether it is reasonable or not. Consider all aspects of your answer (the numerical value, sign, and units) in your evaluation.
What type of diffraction grating should I use so that when sunlight falls on it, I will get all the colors of the rainbow with maximum separation? Give your answer in lines/cm. The visible spectrum goes from 380 nm to 750 nm
Sketch the situation, defining all your variables.
What physics equation(s) will you utilize in order to solve this problem? For each equation you list, give a justification for why it applies to this situation.
Apply your equation(s) to solve, first for an algebraic expression(s), then for any numerical answer(s). Show the units of your answer(s), and how you got them.

a and traveled distance L to the screen where the photograph was made. Consider the width of the central bright fringe,
measured between the centers of the dark fringes on both sides of it. Rank from largest to smallest the widths of the central
fringe in the following situations and note any cases of equality. (Use only ">" or "=" symbols. Do not include any parentheses
around the letters or symbols.)

(b) The experiment is performed with light whose frequency is increased by 50%.
(c) The experiment is performed with light whose wavelength is increased by 50%.
