A laser beam is pointed at a dark shield with two narrow slits. As a result, an interference pattern forms in the space on the other side of the partition. The wavelength is 625 nm, and the first-order bright fringe lies at a 16.6° angle from the central maximum. What is the slit separation (in µm)?
