A pair of narrow, parallel slits in a sheet of black glass are separated by a distance of 0.250 m. The slits are illuminated by light having a wavelength of 546.1 nm. The interference pattern is observed on a screen 1.2 m from the plane of the glass sheet.

a) (6 pts) What is ?, the path difference, between the light rays traveling from the two slits to the first maximum above or below the central maximum?

b) (5 pts) What is the distance on the screen from the first order maximum to the central middle of the maximum?

c) (9 pts) What is the distance between the first and second order dark bands observed in the interference pattern on the screen?
