2. In class you will have seen the equations given above. Note the values recorded: L is the distance from the double-slit grating to the screen (2.5 meters in this case) and d is the distance between slits (.125 mm.) 3. In the next figure you can see the spread of light. Note the central maximum and pairs of bright fringes. I measured the distance between the 2nd bright fringes (m=2) to be 4.2 cm. 4. Using the values recorded above, and the relevant expression(s) from chapter 17, show the work done to find the wavelength of the diode laser, and record the wavelength value below. How does that value compare to the listed range of 660 nm – 680 nm (for red lasers) or 532 nm (for green ones)?

The diagram below illustrates the phenomenon of "missing orders" in the interference pattern made by a double slit. Some orders are missing (that is, there should be a bright fringe but there isn't) because: "Missing orders" Select one: a. Light reaching the screen that passes through different parts of each slit interferes destructively, even though light from the two slits interferes constructively O b. Light reaching the screen from the two slits interferes destructively, even though light that passes through different parts of each slit interferes constructively
