A student and his lab partner create a single slit by carefully aligning two razor blades to a separation of 0.520 mm. When a helium–neon laser at 543 nm illuminates the slit, a diffraction pattern is observed on a screen 1.95 m beyond the slit. Calculate the angle ?dark to the first minimum in the diffraction pattern and the width of the central maximum. a) the angle ?dark to the first minimum in the diffraction pattern (in degrees) b) the width of the central maximum (in m)
