##### Reference no: EM13544747

Two narrow slits are illuminated by a laser with a wavelength of 537 nm. The interference pattern on a screen located x = 5.50 m away shows that the second-order bright fringe is located y = 6.00 cm away from the central bright fringe. Calculate the distance between the two slits? The screen is now moved 0.7 m further away. What is the new distance between the central and the second-order bright fringe?
