Suppose that you shine light from a laser through two slits thatare placed one in front of the other, separated by 0.6mm. The widthof 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 itto what you would expect from single-slit diffraction.
b. If ray (geometrical optics) accurately described thissiutation, 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 thedouble-slit bright spots and the intensity pattern of a single slitof the same width? Do the heights of the peaks seem to follow thesame pattern as the intensity of the single-slit pattern?
