In a given wave double-slit experiment, a detector traces across a screen along a straight line whose coordinate we label y. If one slit is closed, the -y Ze z e-i(wt-ay), is measured. If the other slit is closed, the amplitude Y = 2e 2e-i(wt-ay-by) is measured. What is the intensity pattern along the y axis if both slits are open? amplitude =
