Two narrow slits are illuminated by a laser with a wavelength of 507 nm. The interference pattern on a screen located x = 5.30 m away shows that the third-order bright fringe is located y = 8.70 cm away from the central bright fringe. Calculate the distance between the two slits. The screen is now moved 1.9 m further away. What is thenew distance between the central and the third-order bright fringe?
