Two narrow slits are illuminated by a laser with a wavelength of 593 nm. The interference pattern on a screen located x = 4.80 m away shows that the third-order bright fringe is located y = 9.60 cm away from the central bright fringe. Calculate the distance between the two slits.
The screen is now moved 2.0 m further away. What is the new distance between the central and the third-order bright fringe?
