In a Young's Double Slit experiment, the slit separation d is 0.12 mm. When red light of wavelength 666 nm is used, the resulting interference pattern appears on a distant screen, with the third order bright fringe located at a distance y of 45 mm as measured from the central bright fringe. Calculate the distance (in m) between the slits and the screen. Please quote your answer to two decimal places. The answer is 2.70m, show your work.
