SUMMARY
The width of the second slit in a single-slit diffraction experiment can be determined by analyzing the change in the width of the central bright fringe. Initially, with a slit width of 3.48E-5 m, the central fringe measures 1.37 cm. When a second slit is introduced, the fringe width increases to 1.88 cm. The relationship between slit width and fringe width indicates that the width of the second slit is narrower than the first, calculated using the formula for single-slit diffraction.
