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...

In Young's double-slit experiment, 632.8 nm light from a HeNe laser passes through the two slits and is projected on a screen. As expected, a central maximum (constructive interference) is observed at the center point on the screen. Now, a very thin piece of plastic with an index of refraction n=1.48 covers one of the the slits such that the center point on the screen, instead of being a maximum, is dark. Part A Determine the minimum thickness of the...

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...
