A double-slit diffraction pattern is formed on a distant screen. If the separation between the slits decreases, what happens to the distance between interference fringes? Assume the angles involved remain small. The distance between interference fringes remains the same. The effect cannot be determined unless the distance between the slits and the screen is known. The distance between interference fringes also decreases. The distance between interference fringes increases.

A single-slit diffraction pattern is formed on a distant screen. If the width of the single slit through which light passes is reduced, what happens to the width of the central bright fringe? Assume the angles involved remain small.            The central bright fringe becomes wider.                     The central bright fringe remains the same size.                     The effect cannot be determined unless the distance between the slit and the screen is known.                     The central bright fringe becomes narrower.

4. Light incident on a pair of slits produces an interference pattern on a screen 2.5 m from the slits. Hint: Is the small-angle approximation justified in the following? (a) Determine the wavelength of the light if the slit separation is 0.0150 cm and the distance between adjacent bright fringes in the pattern is 0.760 cm. (b) Determine the distance between adjacent dark fringes if a 560 nm wavelength light source were shined through the same set up.
