A single slit having width d = 0.07 mm is illuminated by light of the two wavelengths, l = 460 nm and l = 659 nm. The diffraction pattern appears on the screen 1.09 m away.
(i) Compute the angles at which the third dark fringe emerges for each wavelength.
(ii) Compute the width of the central bright fringe for each and every wavelength.
