Two 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? m

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.
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 mm

- 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.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_forwardA plane wave hits a piece of glass whose front surface is spherical and whose back surface is plane. The radius of the lens is 10 cm and the thickness of the glass is 1 cm at the center, as shown in the diagram at right. At time t1, the center of the plane wavefront has just reached the lens. A short time later, at time t2, the center of the wavefront will have passed completely through the glass, as shown. a) Find the time that elapses between t1 and t2, the time it takes the center of the wavefront to pass thorugh the middle 1 cm of the glass. b) Find the amount by which the edges of the wavefront at t2 will be ahead of the cetner of the wavefront, due to the fact that these edges passed through empty space, with no glass in their paths.arrow_forward

- 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.arrow_forwardthe 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 responsesarrow_forwardFor the figure shown below, the two sources are 6cm apart, and they are in phase. Two paths are drawn from the sources to a point. (The picture is to scale, even if the sources are not 6cm apart on the paper.)
