Concept explainers
Consider the relative intensity graph shown at right.
Suppose that both slits were made narrower (without changing the distance between the centers of the slits).
On the graph at right, indicate how the relative intensity would change. Explain.
Suppose that after gradually narrowing both slits, one of the slit, were then covered. On the axes provided, sketch the relative intensity graph for this case.
How does your graph compare o what you would expect for a point source? If it is different, how could you modify the physical situation so that the relative intensity graph better approximates that due to a point source?
In order for the relative intensity graph to be a good approximation of that due to a point source, how must the width of the slit compare to A? Explain your reasoning.

- 2 please!arrow_forwardIn a double-slit experiment red light of wavelength λ = 650 nm is shone through two slits separated by a distance d. The second-order dark spot (second dark spot from the center) on the screen (which is much further from the slits than the slit separation d) occurs at an angle of 0.250°. What is the slit separation, d, in mm? Show your work. b) 10 What wavelength of visible light, when shone through the same slits, will yield a bright spot at the same angle? Show your work.arrow_forwardI need help with the question in the attached picture, please be detailed and neat with final solutionsarrow_forward
- Green light shines through a 100-μm-diameter hole and is observed on a screen. If the hole diameter is increased by 20%, does the circular spot of light on the screen decrease in diameter, increase in diameter, or stay the same? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. The wavelets do not interfere in this case The diameter of the central maximum is inversely proportional to the diameter of the hole The diameter of the central maximum is proportional to the diameter of the hole Submit The hole is too large to observe the diffraction increases decreases does not change Request Answer diameter. and so the diameter of the spot of light on the screen Reset with the hole's Helparrow_forwardplease reexplain this paragraph two-beam interference with the double exciter:the circular waves generated by the double exciter are super- posed at the points where they meet. The areas with no wave motion indicate cancellation (minima).the minima and maxima are positioned along hyperbolas with the excitation centers as focal points. the relationships given in the section h0rinciples” for the positions of the hyperbolas are confirmed experimentally.The interference patterns are determined by the distance be- tween exciters, and by the wavelength. the number of hyperbo- las increases with the exciter spacing and the wavelength, and the hyperbolas open further.arrow_forwardSolve the following problems as indicated. Show your complete solutions on a separate sheet of paper. 1. Refer to the illustration on the left. \60° The purple unpolarized light has an 900 original intensity, lo, of 25 W/m?.

- Please use the picture provided to answer the following two questions: 1. are the two sources in phase or out of phase? Explain how you can tell from the diagram. if the two sources are out of phase, give the phase difference between the two sources. Explain. 2. What is the source separation, d, in terms of the wavelength lamda? Explain your reasoning.arrow_forwardAfter passing through a diffraction grating with a period of d = 6.5μm, located 5m away from the screen, laser light creates the image on the screen shown below. What is the wavelength of the light if the distance between zero and first maxima is 50cm? Show all your work.

Continue the incident ray until it emerges through the triangular medium on the other side.

- Please show work and circle answers for parts a and b. Thank youarrow_forwardPlease break down all parts clearly and name equations used! 1. For the antireflective coating shown in the figure, how thick should the coating be to destructively interfere the incoming light and the reflected light (off the front of the glass) and why? Assume the light has a wavelength in air of 533 nm (green). 2. What would the intensity be for 400 nm light and why? (Remember: intensity goes as the electric field squared!) 3. What other wavelengths will completely destructively interfere and why?arrow_forwardPart A Green light shines through a 100-mm-diameter hole and is observed on a screen. If the hole diameter is increased by 20%, does the circular spot of light on the screen decrease in diameter, increase in diameter, or stay the same? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right.
