58. Before the slit width a = 28,5mkm illuminated by monochromatic light beam, a converging lens is placed. On the screen, spaced at l = 10 cm from the lens, diffraction bands are observed. The average distance between the symmetrically arranged bars still Δl = 0,23sm. Determine the wavelength of light λ.
