A red laser pointer with a wavelength of 635 nm is shined on a double slit producing a diffraction pattern on a screen that is1.75m behind the double slit. The central maximum of the diffraction pattern has a width of4.30cm, and the fourth bright spot is missing on both sides. What is the size of the individual slits?
What is the separation between them?
