Red light from a distant point source is incident on a mask with ten identical, evenly-spaced, very narrow slits. (See diagrams at right and below.)
On the magnified view below, label the line segment of length that represent how much farther light must travel from slit 1 than from slit 2 reach point X on a distant screen.

- Suppose 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_forwardTwo 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? marrow_forwardConsider a light ray from a fish that emerges into the air with angle α as shown on the left. Now consider this same light ray originating from the fish going through glass before emerging into the air at angle β, as shown on the right. Which angle is larger: α or β? (Note: the path shown through the glass is illustrative only – you might have to change the slope.arrow_forward
- What 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_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_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_forward
- 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.arrow_forwardhandwritten needed. What is the transmittance, T, for λ = 1,160 nm TE mode light impinging on a glass plate from the air if the angle of incidence is 46° and the index of refraction of the glass at this wavelength is 1.60?

- A ray of sunlight is incident from the left (shown in blue in the upper left) upon a spherical water droplet as shown in figure below. The ray, shown making an angle at incident i undergoes a refraction with angle r at the first interface, a reflection at the rear interface, and finally emerging from a second refraction at the lower front interface. find an expression for the total deviation angle for the returned light ray (lower left in blue) from the incident direction of the light ray, as shown in the figure above. Write your expression in terms of radiansarrow_forwardIn 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_forwardThe speed of light in a particular medium is 1.24x10^8m/s, What is the refreactive index of this medium?
