- *16 Babinet's principle. A monochromatic beam of paral- lel light is incident on a "colli- mating" hole of diameter x> A. Point P lies in the geometrical shadow region on a distant screen (Fig. 36-39a). Two dif- fracting objects, shown in Fig. 36-39b, are placed in turn over the collimating hole. Object A is an opaque circle with a hole in it, and B is the "photographic negative" of A. Using superpo- sition concepts, show that the intensity at P is identical for the two diffracting objects A and B. Screen (a) (6)While washing dishes one evening, you admire the swirling colors visible in the soap bubbles. You hold up a cup and peer into its soap‑covered mouth. As you hold the cup still and examine it in the light of a lamp behind you, you notice that the colors begin to form horizontal bands, as in the figure. You observe that the film appears black near the top, with stripes of color below. Approximately how thick is the film of soap in the reddish region of the second stripe indicated? Assume that the film is nearly perpendicular both to your line of sight and to the light rays from the lamp. For simplicity, assume that the region specified corresponds to the second maximum of the intensity of reflected red light with a 645 nm wavelength. The index of refraction of the soap film is 1.34.A thin film of water of thickness 220nm is placed on top of a glass surface. What color will the film appear when viewed directly from the top? - Yellow - Red - Green -black - Blue
- Two narrow slits separated by 0.38 mm are positioned a distance 4.5 m away from a screen. Two lasers illuminate the slits with wavelengths 655 nm and 524 nm, creating a pattern of overlapping interference patterns on the screen. The central maxima (m = 0) of both colors overlap at y = 0. What is the next higher position y > 0 where maxima for both colors overlap again? Give your answer in units of mm.3. If on a glass plate with refractive index 1.52, rests a soap bubble of thickness 742nm with n=1.33, what will be the colours seen on the soap bubble.Hi, can I please get some help solving this question? Thank you!
- A thin layer of oil floats on a puddle of water. When sunlight hits the film from directly above, the colors red (650 nm) and violet (390 nm) are reflected. What is the minimum thickness of the oil? Use n=1.5 for the oil, and n=1.33 for water.A glass sheet measuring 15.0 cmcm ×× 29.0 cmcm is covered by a very thin opaque coating. In the middle of this sheet is a thin, straight scratch 0.00125 mmmm thick, as shown in (Figure 1). The sheet is totally immersed beneath the surface of a liquid having an index of refraction of 1.41. Monochromatic light strikes the sheet perpendicular to its surface and passes through the scratch. A screen is placed under the liquid a distance 32.0 cmcm away from the sheet and parallel to it. You observe that the first dark fringes on either side of the central bright fringe on this screen are 23.0 cmcm apart. What is the wavelength of the light in air? Express your answer in nanometers.White light strikes (a) a diffraction grating and (b) a prism.A rainbow appears on a wall just below the direction ofthe horizontal incident beam in each case. What is the colorof the top of the rainbow in each case? Explain.
