For a demonstration, a professor uses a razor blade to cut a thin slit in a piece of aluminium foil. When she shines a laser pointer (?=680nm) during the slit onto a screen 5.5m away, a diffraction pattern appears. The bright band in the center of the pattern is 7.8cm wide. What is the width of the slit?
