Suppose that you shine light from a laser through two slits that are placed one in front of the other, separated by 0.6mm. The width of each slit is 0.12mm. The light will travel from the laser, through the slits, and onto a screen 1.5m away.

a. Predict what you will observe on the screen, and compare it to what you would expect from single-slit diffraction.

b. If ray (geometrical optics) accurately described this siutation, what would the pattern on the screen look like? Explain.

c. How would the pattern change if you used narrower slits?

d. How would the pattern change if you used wider slits?

e. Draw a graph showing the relationship between intensity (y-axis) and distance across the screen (x-axis).

f. Is there a relationship between the maximum intensity of the double-slit bright spots and the intensity pattern of a single slit of the same width? Do the heights of the peaks seem to follow the same pattern as the intensity of the single-slit pattern?

Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at \pm 35.09 degrees on either side of the central bright spot. You then immerse these slits in a transparent liquid and illuminate them with the same light. Now you find that the first minima occur at \pm 19.48 degrees instead. a) What is the index of refraction of this liquid? Express your answer using four significant figures.
