# Question

Two parallel slits are illuminated with monochromatic light, and an interference pattern is observed on a screen.

(a) If the distance between the slits were decreased, would the distance between the maxima (1) increase, (2) remain the same, or (3) decrease? Explain.

(b) If the slit separation is 1.0 mm, the wavelength is 640 nm, and the distance from the slits to the screen is 3.00 m, what is the separation between adjacent interference maxima?

(c) What if the slit separation is 0.80 mm?
