2. Green light with a frequency of 6 x 10¹4 Hz is shined on two slits separated a distance of 5 x 10-5 m. The detector screen is located 1.5 m away. a) Treating the slits as point-like, how far above the center of the detector is the first dark fringe? How about the first bright fringe (excluding the bright fringe at the center)? b) Consider the second dark fringe above the center of the detector and the first bright spot below the center of the detector, how far apart are these locations? c) Would your answer to a) increase, decrease, or stay the same if the light was violet? What if it was red?

Interference of light waves through two slits: When the light wave from the same source is made to pass through two slits of point size separated by a distance , then they form an interference pattern on the screen placed at distance from the slits.
Position of maxima: The position of order maximum (or bright fringe) on the screen is given by the equation,
where is the wavelength of light, is the position of the bright fringe from the central maximum and is an integer.
Position of minima: The position of order minimum (or dark fringe) on the screen is given by the equation,
where is the position of the dark fringe from the central maximum and is an integer.
