A Young’s double-slit apparatus is illuminated with 669 nm light and the screen is positioned 2.2 m from the double slits. If the spacing between the two slits is 0.33 mm …

Part a) What is the angle from the center line (the line from the center of the two slits to the central bright spot) to the second order bright spot?

Part b) What is the distance from the zeroth order bright fringe and on the screen to the second order bright spot on the screen?
