The spacing on the slits slide is probably the separation between the slits and not the spacing. You should project an image of the slits with the overhead projector to verify.
In the second portion of today's experiment, we will also explore the interference pattern produced by two slits, often known as Young's double-slit experiment , in honor of Thomas Young who performed this experiment in the early 19 th century.
In two-slit interference, light falls on an opaque screen with two closely spaced, narrow slits. Each slit then acts as a new source of light. Because the slits are illuminated by the same wave front, the sources are in phase.
If the light passes through two slits of width a, separated by a distance d, then the intensity pattern at the screen is the same single slit diffraction pattern, but modulated by the interference caused by the two slits!
Theory - Multiple Slits and Gratings One might ask about what happens when we have more then two slits, lets say 3, 4, or a 1000. It can be shown that in this case, the position of the maxima is given by the same equation as the equation used for two slits.
Which of the following forms an interference pattern when directed toward two suitably-spaced slits? (1) all of these (2) electrons (3) sound (4) light (5) none of these Sound, electrons, and light all are waves in one sense or another and so will form an interference pattern, as we discussed in class.
TJ 18 (1) 2004 71 Essays Human embryonic gills and gill slits—down but not out Jerry Bergman A survey of recent biology textbooks and popular science literature shows that while most authors no longer use the idea that a human embryo develops 'gills' and 'gill slits', some still retain this ...
What is emitted when an electron is 'fired' is a burst of energy which propagates continuously as a wave and going through both slits illuminates the detection screen in the typical interference pattern.

Since the ocean floor gets cooler and more dense as the material moves toward the side slits, the depth of the ocean floor increases. 4. What do the stripes on the strips stand for?
