Send light through a narrow slit and it fans out into a bright central band flanked by dimmer fringes — diffraction. The pattern follows a sinc-squared curve, with the first dark fringe where the path difference across the slit equals one wavelength. Narrower slits spread the light more, the diffraction limit that caps every lens and telescope's sharpness.

Governing equation
Reading this result: Wide slit relative to the wavelength: the central peak is tight and the beam stays nearly collimated, with only faint fringes.
