A laser beam with wavelength 632.8 nm is incident on two narrow slits separated by 0.22 mm. Calculate how far apart the resultant interference fringes on a screen will be if it is located 2.3 m away from the slits?
Monochromatic light falls on two very narrow slits 0.048 mm apart. Successive fringes on a screen 6.00 m away are 8.5 cm apart near the center of the pattern. Determine the wavelength and frequency of the light.
A diffraction experiment involving two thin parallel slits yields the pattern of closely spaced bright and dark fringes shown in the following figure. Only the central portion of the pattern is shown in the figure. The bright spots are equally spaced at d = 1.57 mm center to center (except for the missing spots) on a screen 2.15 m from the slits. The light source was a He-Ne laser producing a wavelength of 632.8 nm. (a) How far apart are...

A red laser from the physics lab is marked as producing 632.8-nm light. When light from this laser falls on two closely spaced slits, an interference pattern formed on a wall several meters away has bright red fringes spaced 6.00 mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 6.18 mm apart. What is the wavelength of light produced by the pointer?
Light with a wavelength of 520 nm passes through 0.25 mm slits that are 1.0 mm apart. An interference pattern is seen on a screen that is 2.5 m away. How far from the center is the first dark fringe due to the slit width? How far from the center are the bright fringes that fall within this distance?
