Textbook Question
Chapter 14.1, Problem 1cT
Suppose that a single change were made to the apparatus (keeping the distance between the mask and the screen fixed), resulting in the new pattern shown.
1. Are the angles to the interference maxima in the new pattern greater than, less than, or equal to those in the original pattern? Explain how you can tell from the photographs.
2. If the
3. If the slit separation (d) was the only quantity changed, determine (i) whether d was increased or decreased, and (ii) whether it was changed by a factor that was greater than, less than, or equal to 2. Explain how you can use your results from parts A and B to justify your answer.

If light with a wavelength of 480 nm is used in a two-slit experiment with a barrier with slits that are 0.05 mm apart that is 1.6 m from the projection screen. What is the distance from the center of the first and third dark fringes? Show your work.
As shown is the interference pattern seen on a viewing screen behind 2 slits. Suppose the 2 slits were replaced by 20 slits having the same spacing d between adjacent slits.a. Would the number of fringes on the screen increase, decrease, or stay the same?b. Would the fringe spacing increase, decrease, or stay the same?c. Would the width of each fringe increase, decrease, or stay the same?d. Would the brightness of each fringe increase, decrease, or stay the same?
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.

- A thin beam of white light is directed at a flat sheet of silicate flint glass at an angle of 20° to the surface of the sheet. Due to dispersion in the glass, the beam is spread out in a spectrum as shown in the figure. The refractive index of silicate flint glass versus wavelength is graphed in figure to the right. (a) The rays (A and B) shown in the figure correspond to the extreme wavelengths. Which corresponds to red and which to violet? Explain your reasoning. (b) For what thickness of the glass sheet will the spectrum be 1.0 mm wide, as shown (see Problem 7)? Hint: you must first solve Problem 7 first before doing Problem 8). Answer: 93.5 mmarrow_forwardDiscuss the two cases, constructive and destructive interferences, as a result of thin-film interference. (Provide figure/s to support your statement.)arrow_forwardAn array of 100 slits per millimetre is illuminated with light made up of a mixture of 3 wavelengths: a shade of violet, a shade of green and a shade of red. On a screen 2 meters away, we see the figure shown in the diagram below. Determine as precisely as possible the wavelength of each color.arrow_forward

How does a double slit affect the wave pattern?arrow_forwardConsider the interference pattern at the right. (The crests are represented by thick lines and the troughs by thin lines.) The distance from S1 to point D is 47.2 cm. What is the wavelength? What is the distance from S2 to point D?arrow_forwardSuppose that the simulated light source was polychromatic, with both a red and a yellow component, as shown on the right. How easy would it be to identify the positions (yP ) of the separate red and yellow interference maxima? Can you think of a change in the appearance of the interference pattern of each individual wavelength that, were it to happen, would help to distinguish the red from the yellow peaks?arrow_forward
- Please show formula and units For the figure shown below, let R = 1.20 m and d = 0.120 mm and assume the slit system is illuminated with monochromatic 500 nm light. The first bright fringe (m = 1) happens at point P. Calculate the phase difference (ϕ) between the two wave fronts arriving to point P in radians when: a) θ = 0.500⸰ b) y = 5.00 mm. The value of θ in part b is not the same as the value of θ from part a. However, you may assume that θ in part b is small.arrow_forwardA narrow beam of white light enters a prism made of crown glass at a 45° incident angle, as shown in attached figure 1. At what angles, θR and θV, do the red (660 nm) and violet (410 nm) components of the light emerge from the prism? Feel free to use the table attached for the indices of refraction as a function of wavelength. How would I derive the outgoing angle as a function of the incoming angle and the index of refraction. As I am struggling with this question, any help would be greatly appreciated :)arrow_forwardMay you answer the question in the image attached below. Also, the answer is not 176 nm. I have tried using it, and it was marked as incorrect because "You may have confused the expressions of constructive and destructive reflection. To find the smallest thickness of the grease layer, recall the definition of the constructive reflection." Thank you.arrow_forward
- If the incident ray at point A is at the critical angle between mediums 2 and 3, does the ray incident at point B refract out of medium 2 into 3? If so, what is the (i) angle of refraction at point B? If not, what is the reflected angle at point B? (ii) Draw an accurate ray diagram at point B. (iii) What is the initial angle θ at point C?arrow_forwardYou 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.arrow_forwardA narrow beam of light is incident on the left side of the prism shown in the figure below. The prism is a right triangle, with two of its angles measuring 45°. A) The transmitted beam that exits the hypotenuse of the prism makes an angle of ? = 17.5° with the direction of the incident beam. What is the index of refraction of the prism? B) In part (a), we assumed the beam was monochromatic. Consider instead the case where the beam was composed of white light. Because the index of refraction differs for different wavelengths, the white light would be dispersed into constituent colors. Assume the index of refraction for blue wavelengths is 1.01n and for red wavelengths it is 0.99n, where n is the index of refraction found in part (a). What is the angular spread (in degrees) between red and blue light exiting the prism?arrow_forward
