Problem

A single slit of width 0.10 mm is illuminated with light of wavelength 700 nm. A screen 2.5 m away is 1.0 m wide (extending 0.50 m to either side of the central axis). Determine whether the first diffraction minimum will appear on the screen, and support your answer with a brief numerical check.
