A rectangular glass chamber is inserted into one arm of a Michelson interferometer using a 633-nm light source. This chamber is 5.401 cm long, and initially it is filled with air n=1.000293 at standard atmospheric pressure.
The air is gradually pumped out using a vacuum pump until a nearly perfect vacuum is achieved. How many fringes are observed moving past a fixed point on the screen during the transition? (An integer answer is required.)

Solved in 4 steps with 4 images
- A plane wave with a wavelength of 605 nm is incident normally on a single slit with a width of 3.98 x 10m. Consider waves that reach a point on a far-away screen such that rays from the slit make an angle of 2.00° with the normal. The difference in phase for waves from the top and bottom of the slit (in rad) is i rad.A broad beam of light of wavelength 600 nm is sent directly downward through the glass plate (n = 1.41). That plate and a plastic plate (n = 1.24) form a thin wedge of air that acts as a thin film. An observer looking down through the top plate sees the fringe pattern, with 7 dark fringes, having two centered on the ends. (a) What is the thickness (in m) of wedge at the right end? (b) How many dark fringes will the observer see if the air between the plates is replaced with a liquid with n = 1.35?Monochromatic, in phase light of wavelength > 752nm is incident on a piece of metal with either one or two slits on it - it is difficult to see to determine which. The diffraction pattern is observed on a viewing screen that is located 55cm away from the metal plate. The first two minima are measured to be 2.3cm and 7.0cm away from the central maxima. What is the brightness of the light at a distance of 6.3cm from the central maxima, relative to the brightness of the central maxima? x10-3 Note: Brightness is proportional to the SQUARE of the amplitude. For double slit, this means I = I (cos(d sin ) º)) ². 2 I = I₂ sin (5) xd sin 0 . For single slit, this means In both of these, I, is the maximum brightness, and d is the characteristic spacing of the slit(s).
- Sound waves with frequency 2600 Hz and speed 343 m/s diffract through the rectangular opening of a speaker cabinet and into a large auditorium of length 100 m. The opening, which has a horizontal width of 38.7 cm, faces a wall 100 m away (the figure below). Along that wall, how far from the central axis of that wall in meters will a listener be at the first diffraction minimum and thus have difficulty hearing the sound? (Neglect reflections.)A technician is performing Young's double-slit experiment for his supervisor. He directs a beam of single-wavelength light to a pair of parallel slits, which are separated by 0.132 mm from each other. The portion of this light that passes through the slits goes on to form an interference pattern upon a screen, which is 4.50 meters distant.The light is characterized by a wavelength of 590 nm. (a)What is the optical path-length difference (in µm) that corresponds to the fifth-order bright fringe on the screen? (This is the fifth fringe, not counting the central bright band, that one encounters moving from the center out to one side.) ?µm (b)What path-length difference (in µm) corresponds to the fifth dark fringe that one encounters when moving out to one side of the central bright fringe? ?µmTwo slits separated by a distance of d=0.150 mm are located at a distance of D=810. mm from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by a coherent light source with a wavelength of λ=549×10−6 mm. The interference pattern shows a peak at the center of the screen (m=0) and then alternating minima and maxima. (a) What is the path length difference in millimeters between the two waves from the two slits at the first (m=1) maximum on the screen? (b) What is the path length difference in millimeters between the two waves from the two slits at the first (m=0) minimum on the screen? (c) Calculate the distance on the screen between the central maximum (m=0) and the first (m=1) maximum. You can assume sinθ≈tanθ≈θ, with θ expressed in radians. Give your answer in millimeters.
- Laser light of wavelength 627.0 nm passes through a double-slit arrangement at the front of a lecture room, reflects off a mirror 29.2 m away at the back of the room, and then produces an interference pattern on a screen at the front of the room. The distance between adjacent bright fringes is 9.52 cm. What is the slit separation in meters? Number i 0.000192 Units mA vehicle with headlights separated by 2.00 m approaches an observer holding an infrared detector sensitive to radiation of wavelength 885 nm. What aperture diameter is required in the detector if the two headlights are to be resolved at a distance of 10.0 km?A beam of light of wavelength 691 nm passes through two closely spaced glass plates, as shown in the figure.For what minimum nonzero value of the plate separation d will the transmitted light be bright? (This arrangement is often used to measure the wavelength of light and is called a Fabry-Perot interferometer.)
