When the slits are very close together, it is as if there were just one slit, and we see a basic diffraction pattern, however once we spread out the slits, we can start to see interference when waves passing through the two different slits interfere with each other. Confirm your prediction above and write your observation of the difference in the diffraction patterns between spacings less than and greater than the wavelength size.

When the width of the slit is made double, how would this effect the size and intensity of the central diffraction band? Justify your answer with the help of diagram.
Discuss the two cases, constructive and destructive interferences, as a result of thin-film interference. (Provide figure/s to support your statement.)
the central part of the interference pattern for a pure wavelength of red light projected onto a double slit.The pattern is actually a combination of single slit and double slit interference. Note that the bright spots are evenly spaced. Isthis a double slit or single slit characteristic? Note that some of the bright spots are dim on either side of the center. Is this asingle slit or double slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses
The diffraction pattern below arises from a single slit. If we would like to sharpen the pattern (i.e., make the central bright spot narrower), what should we do to the slit width? a) widen the slit b) enlarge the screen c) close off the slit d) None of the other responses are correct.
The experiment described in question 2 above is performed, but this time, a strip of transparent plastic is placed over the left slit. Its presence changes the interference between light waves from the two slits, causing the interference pattern to be shifted across the screen from the original pattern. Explain, clearly but briefly, which way (right or left) the original pattern shifts and why this shift occurs.
You just won a brand new laser pen and you want to know the wavelength of the light, so you set up Young’s double-slit experiment and observe the interference pattern on screen 1.2 meters away from the slits. The slits are 0.25 mm apart and you measure the distance between the centers of the first dark fringes on either side of the central maximum to be 3 mm. What is the wavelength of your new laser? If visible, what color should it appear, if not visible state the region of the EM spectrum? Hint: Draw a picture.
Two radio antennas separated by d = 270 m, as shown in the figure below, simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1,030 m from the center point between the antennas, and its radio receives the signals. Hint: Do not use the small-angle approximation in this problem. (a) If the car is at the position of the second maximum after that at point O when it has traveled a distance of y = 400 m northward, what is the wavelength of the signals? m(b) How much farther must the car travel from this position to encounter the next minimum in reception? m
While researching the use of laser pointers, you conduct a diffraction experiment with two thin parallel slits. Your result is the pattern of closely spaced bright and dark fringes shown in (Figure 1) (Only the central portion of the pattern is shown.) You measure that the bright spots are equally spaced at 1.53 mm center to center (except for the missing spots) on a screen that is 2.50 m from the slits. The light source was a helium–neon laser producing a wavelength of 632.8 nm. How far apart are the two slits? How wide is each slit?
How does the geometry of the diffraction experiment setup (slit size, and screen- to-slit distance) and properties of light (wavelength) relate to the properties of the diffraction pattern (width, location, and intensity of the fringes)?
The analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. Consecutive bright bands on an interference pattern are 3.5 cm apart when the slide containing the slits is 10.0 m from the screen. The slit separation distance is 0.050 mm. y= ________ d=________ m=_______ L=________
How does the geometry of the diffraction experiment setup (slit size, and screen- to-slit distance) and properties of light (wavelength) relate to the properties of the diffraction pattern (width, location, and intensity of the fringes)? The initial answer provided by Bartleby is incomplete and inaccurate.
In a Young's double-slit experiment, blue light (?λ = 440 m) gives a second-order bright fringe at a certain location on a flat screen. What wavelength of visible light would produce a dark fringe at the same location? Assume that the range of visible wavelengths extends from 380 to 750 nm. Calculate the wavelength that fulfills the problem description. Clearly show all steps, starting from generalized equations. Explain your mathematical work in words. Your explanation should cover both what you did, any approximations you make and the thought process behind why you did that. Evaluate your answer to determine whether it is reasonable or not. Consider all aspects of your answer (the numerical value, sign, and units) in your evaluation.
