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 5.50 mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 5.68 mm apart.

Part A

What is the wavelength of light produced by the pointer?

Express your answer to three significant figures and include the appropriate units.

A physics student demonstrates Young's double-slit experiment using 632.8 nm light from a HeNe laser. The laser light passes through two narrowly separated slits that have a spacing of d. The light produces an interference pattern on a screen that is 4.20 meters in front of the slits. The spacing between the m=2 and m=3 maxima as seen on the screen is 12.0 cm. Determine the spacing between the slits. For the situation described above, determine the phase difference between...

You and a friend are running some physics experiments to test the wave nature of light. To do so, you cut two very narrow slits on a black plastic sheet, separated by 0.150 mm, and shine coherent light from a laser pointer through them. According to the label on your friend’s laser pointer, it emits coherent light at 570 nm, while your laser pointer doesn’t have any information about the wavelength of light emitted. You then observe their respective interference...

To test some of the principles of physics a team of scuba divers sets up a double slit experiment under water in a swimming pool. Red light is emitted by a laser (kept out of the water), and has a wavelength of 632.8 nm in air. The laser beam is directed by mirrors to a double slit located near the bottom of the pool. Just before the light strikes the double slit it is traveling horizontally about a 1⁄2 meter...

A physics instructor wants to produce a double-slit interference pattern large enough for her class to see. For the size of the room, she decides that the distance between successive bright fringes on the screen should be at least 2.60 cm. If the slits have a separation d=0.0165mm, what is the minimum distance from the slits to the screen when 632.8-nm light from a He-Ne laser is used?

Interference with light We aim a red (620 nm) laser onto a small screen that has two slits that are 0.1 mm apart. Each slit has a width of 0.03 mm. The light coming out of the two slits is projected onto a big screen a distance X from the slits. In the photo on the right you can see the pattern that’s visible on the big screen. Using a ruler, we determine that the distance between two adjacent bright...
