When I shine a green laser pointer (wavelength 532nm) on two slits, I find that what should be the central bright spot is actually a dark spot. Upon further investigation, I discover that there's a thin layer of oil covering one of the slits. The oil has an index of refraction of 1.5. What is the minimum thickness of the oil that would cause the observed effect?

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?

You have a red laser (wavelength 656 nm) that produces a beam wide enough to illuminate two large slits. Each slit is 1.0 cm wide, and they are 4.0 cm apart. The laser light shines through the slits onto a viewing screen 1.00 m away. a. Describe what will be seen on the viewing screen. Draw a picture. Label the picture with any relevant physical distances that you can determine. The slits are replaced with much smaller ones. They are...

2. Laser light with wavelength 1 = 600 nm is sent through a screen with N narrow slits spaced a apart from each other (e.g. if there are 3 slits, they are at 0, a, 2a). You observe the resulting diffraction pattern on a screen placed far (meters) away. The screen is curved, so that the distance of the screen to the slits is constant with angle. This simplification means you don't have to take into account longer paths for...
