Light with a wavelength of 600 nm (6 x 10^-7 m) passes through two slits separated by just 0.03 mm (3 x10^-5 m). A fringe pattern is observed on a screen placed 1.2 m from the double slit.
a. How far from the center of the screen will the first bright fringe appear on either side of the central fringe?
b. Where will the second bright fringe appear on either side?
c. At what distance from the center of the screen will the first dark fringe appear on either side?
d. Sketch a diagram showing the positions of the seven central bright fringes (the center fringe and three fringes on either side of the center fringe). Clearly indicate the distance of each fringe from the center of the screen
