If you have a light wave that travels through a couple of slits which are .174 mm apart, the light travrls to a screen which is 1.3 m away and forms a pattern that has its first bright fringe at a distnace of 3.5 mm from the middle fringe what would you say the wavelength of the source light is? How would pattern change if distance between slits doubles?
