SUMMARY
The diffraction problem involves calculating the slit width for light of wavelength 680 nm falling on a single slit, with a diffraction pattern observed on a screen 50 cm away. The distance between the first and third minima is given as 3 mm. The correct formula to use is y = m*lambda*R/a, where 'y' is the distance between minima, 'm' is the order of the minima, 'lambda' is the wavelength, 'R' is the distance to the screen, and 'a' is the slit width. The correct calculation shows that the slit width 'a' is 1.7 x 10^-4 m after accounting for the correct minima positions.
