Astudent and his lab partner create a single slit by carefully aligning two razor blades to a separation of 0.530 mm. when a helium–neon laser at 543 nm illuminates the slit, a diffraction pattern is observed on a screen 1.55 m beyond the slit. calculate the angle θdark to the first minimum in the diffraction pattern and the width of the central maximum.
