The monochromatic light diffracts on the two slits which are 0.1 mm apart (their size is negligible) andproduces an interference pattern on the wall which is 3 m far from the apparatus. a) The distance between the central bright fringe and the first off-center bright fringe is 2 cm. Whatis the wavelength of the light? Which color is it?b) How many bright fringes could we see on the wall?c) We change the film with slits and the distance between adjacent dark fringe and bright fringe is7 mm. What is the distance between two slits now?
