Question

Light passes through a single slit and shines on a flat screen that is located 0.4 m away.
The width of the slit is 4 x 10-6 m. Determine the width of the central bright fringe for
violet light (wavelength of 410 nm). Draw a sketch to support your answer. (I know the answer is 0.083 m. I just want to see the process and the sketch)
