Question

In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 517 nm. An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.3 m and the distance between the two slits is 0.118 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the screen?
