Concept explainers
Monochromatic light from a distant point source is incident on two slits. The width of each slit is a and the distance between the centers of the slits is d. The resulting graph of relative intensity versus θis shown at right. (The center of the pattern is at
Sketch the relative intensity graph that would result when each of the following changes is made. Your graphs should show the approximate locations of the maxima and minima and be qualitatively correct as to the relative sizes of the maxima. Explain your reasoning.
c. A third slit of width a is added to the right of the existing slits, while keeping the distance between adjacent slits (d) fixed.

Introduction to Electrodynamics
- 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.arrow_forwardWhat minimum path length is needed to introduce a phase shift of 205° in light of wavelength 566 nm? (Give your answer in nm.) What phase shift will that path difference you calculated in part (a) introduce in light of wavelength 799 nm? (Give you answer in degree.)arrow_forwardDiscuss the two cases, constructive and destructive interferences, as a result of thin-film interference. (Provide figure/s to support your statement.)arrow_forward
- Solve the following: (show your complete solution) (a) At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00 µm? (b) Will there be a second minimum?arrow_forwardTwo slits of width 3 μm, each in an opaque material, are separated by a center-to-center distance of 7.5 μm. A monochromatic light of wavelength 400 nm is incident on the double-slit. One finds a combined interference and diffraction pattern on the screen. How many peaks of the interference will be observed in the central maximum of the diffraction pattern? Please show all the work! Thanks!arrow_forwardIf 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.arrow_forward
- 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.arrow_forwardAn intereference pattern is produced by light with a wavelength of 560 nm from a distant source incident on two identical parallel slits seperated by a distance (between centers) of 0.580 mm. (A) if the slits are very narrow what would be the angular position of the first order two slit intereference maxima? Express your answer in radians. (B) what would be the angular position of the second order two slit intereference maxima in this case?arrow_forwardTwo radio antennas separated by d = 294 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 = 1,080 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. Two antennas, one directly above the other, are separated by a distance d. A horizontal dashed line begins at the midpoint between the antennas and extends to the right. A point labeled O is a horizontal distance x from the line's left end. A car is shown to be a distance ydirectly above point O. An arrow extends from the car, indicating its direction of motion, and points toward the top of the page. (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 mnorthward, what is the wavelength of the signals?answer in m(b) How much farther must the car travel to encounter the…arrow_forward
- Please show work and circle answer A laser beam of wavelength 670 nm shines through a diffraction grating that has 750 lines/mm. Sketch the pattern that appears on a screen 1.0 m behind the grating, noting distances on your drawing and explaining where these numbers come from.arrow_forwardDerive the transmission and reflection coefficient of monochromatic plane wave propagating from non conducting incident to conducting incident. Assume that the incident wave hits perpendicular to the medium. Can you please help me with this problem show a complete and explicit solution with an explanation step by step. Note: No shortcuts and don't skip any mathematical algebra.arrow_forwardUse the following information for the Gas Identification part of the lab. The data below are angles that might be recorded by a student using a spectrometer to map bright lines in the emission spectrum of some unknown gas. Be sure to record both the gas ID number and the diffraction grating constant (slit spacing) to be used in the analysis. In the answer field below, convert the first m=1 angle entry above to the corresponding wavelength expressed in nanometres. PLEASE SHOW THE STEPS FOR HOW TO CALCULATEarrow_forward
