Concept explainers

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

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 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
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.
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?
Given the data below, calculate the distance between side orders, Δy_1 (cm) and distance between side orders, y_1 (cm) if m=1 and slit width (cm) is equal to: 0.02, 0.04, 0.08, 0.16. Explain/show how calculations were made.***If the information I have provided is incomplete, please reply with the additional information needed so I can fix it.
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.
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.
Using Figure 36.6 as a model, sketch the interference pattern from six slits. Figure 36.6 Multiple-slit interference patterns. As N, the number of slits, is increased, the primary maxima (the tallest peaks in each graph) become narrower but remain fixed in position and the number of secondary maxima increases.
Shown below is 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 singleand double-slit interference. Note that the bright spots are evenly spaced. Is this a double- or single-slit characteristic? Note that some of the bright spots are dim on either side of the center. Is this a single- or double-slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses.
Answer the following questions : (i) In what way is diffraction from each slit related to the interference pattern in a double slit experiment? (ii) When a tiny circular obstacle is placed in the path of light from a distance source, a bright spot is seen at the centre of the shadow of the obstacle. Explain, why.
Sketch and explain the pattern that would have been on the screen of a single-slit setup if light were only to behave as particles. Attached is an image that shows how waves and particles would differ on passing through a slit. Please see this as a reference.
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.
What is the basic condition for diffraction observation? Explain. Obtain the expression that gives the illumination pattern of diffraction in a single slit by using a figure.
