PredictfCalculate Sodium light, with a wavelength of λ = 589 nm, shines downward onto the system shown in Figure 28-47. When viewed from above, you see a series of concentric circles known as Newton’s rings. (a) Do you expect a bright or a dark spot at the center of the pattern? Explain. (b) If the radius of curvature of the plane-convex lens is R = 26.1 m, what is the radius of the tenth-largest dark ring? (Only rings of nonzero radius will be counted as “rings.”)

- A ray of 610 nm light goes from air into fused quartz at an incident angle of 55.0°. At what incident angle must 470 nm light enter flint glass to have the same angle of refraction?arrow_forwardBy how much do the critical angles for red (660 nm) and violet (410 nm) light differ in a diamond surrounded by air?arrow_forwardIf b is Brewster's angle for light reflected from the top of an interface between two substances, and b is Brewster's angle for light reflected from below, prove that b+b=90.0.arrow_forward
- Light travels from air into glass. Which sketch in Figure 38.2 correctly shows the incident, reflected, and refracted beams? Hint: Consider the law of reflection (Section 37-2).arrow_forwardConsider a common mirage formed by superheated air immediately above a roadway. A truck driver whose eyes are 2.00 m above the road, where n = 1.000 293, looks forward. She perceives the illusion of a patch of water ahead on the road. The road appears wet only beyond a point on the road at which her line of sight makes an angle of 1.20 below the horizontal. Find the index of refraction of the air immediately above the road surface.arrow_forwardCalculate the wavelength of light that has its third minimum at an angle of 30.0° when falling on double slits separated by 3.00 m. Explicitly show how you follow the steps from the Problem-Solving Strategy: Wave Optics, located at the end of the chapter.arrow_forward
- While using a Michelson interferometer (shown in Fig. 37.13), you see a dark circle at the center of the interference pattern, (i) As you gradually move the light source toward the central mirror M0, through a distance /2, what do you see? (a) There is no change in the pattern, (b) The dark circle changes into a bright circle. (c) The dark circle changes into a bright circle and then back into a dark circle. (d) The dark circle changes into a bright circle, then into a dark circle, and then into a bright circle. (ii) As you gradually move the moving mirror toward the central mirror M0, through a distance /2, what tit) you see? Choose from the same possibilities.arrow_forwardWhat is most likely to happen to a beam of light when it reflects from a shiny metallic surface at an arbitrary angle? Choose the best answer, (a) It is totally absorbed by the surface, (b) It is totally polarized, (c) It is un-polarized. (d) It is partially polarized, (e) More information is required.arrow_forwardFigure CQ37.2 shows an unbroken soap film in a circular frame. The film thickness increases from lop to bottom, slowly at first and then rapidly. As a simpler model, consider a soap film (n = 1.33) contained within a rectangular wire frame. The frame is held vertically so that the film drains downward and forms a wedge with flat faces. The thickness of the film at the top is essentially zero. The film is viewed in reflected white light with near-normal incidence, and the first violet ( = 420 nm) interference band is observed 3.00 cm from the top edge of the film, (a) Locate the first red ( = 680 nm) interference band, (b) Determine the film thickness at the positions of the violet and red bands, (c) What is the wedge angle of the film?arrow_forward
- A narrow beam of white light enters a prism made of crown glass at a 45.0° incident angle, as shown in Figure 25.57. At what angles, R and V, do the red (660 nm) and violet (410 nm) components of the light emerge from the prism? Figure 25.57 This prism will disperse the while light into a rainbow of colors. The incident angle is 45.0°, and the angles at which the red and violet light emerge are R and V.arrow_forwardBy how much do the critical angles for red (660 nm) and violet (410 nm) light differ in a diamond surrounded by air?arrow_forwardThe limit to the eye's acuity is actually related to diffraction by the pupil. (a) What is the angle between two just-resolvable points of light for a 3.00-mm-diameter pupil, assuming an average wavelength of 550 nm? (b) Take your result to be the practical limit for the eye. What is the greatest possible distance a car can be from you if you can resolve its two headlights, given they are 1.30 m apart? (c) What is the distance between two just-resolvable points held at an arm's length (0.800 m) from your eye?
