1) A two-slit interference experiment uses laser light of wavelength 655 nm. The slits are 0.230 mm apart and 1.75 m from the screen on which the interference pattern appears. The intensity of the light at the central bright fringe is I(max) = 0.0520 W/m2. Find the intensity at a point on the screen 6.50 mm from the central bright fringe. 2) Find the distance on the screen from the central bright fringe to the nearest point where the intensity is I(max)/4.
Kindly include explanations as well, thank you!
