XX Light from a laser passes through two very narrow slits as shown in the top view diagram at right. The Y Z photograph shows what appears on a screen that is far Pattern from the mask. The screen is bright at points X and Y and dark at point Z 1. If the left slit were covered, would the brightness at each of the following points increase, decrease, or stay the same? Explain. Point Y on screen . Point Z 2. Suppose that the distance separating the slits is changed (without changing the width of the slits). The new pattern on the screen is shown at right a. Was the slit separation increased or decreased? Explain Original patte on screen New pattern on screen Center of screen b. Suppose that, instead of changing the slit separation, the wavelength of the laser light was changed. The effect on the pattern is identical to that shown above. Was the wavelength increased or decreased? Explain.
