A student shines a red laser pointer with a wavelength of 675 nm through a double-slit apparatus in which the two slits are separated by 75.0 µm. He observes the diffraction pattern on the wall 1.50 m away. What is the distance between the central bright fringe and either of the neighbouring bright fringes on the wall?
