An interferometric hologram is produced by exposing the film twice, once when the object is unstressed and once when it is stressed, causing it to flex slightly. The resulting hologram has light and dark bands that are analogous to the interference fringes of an air wedge. If 22 bright fringes are observed between one side of an object and the other when the hologram is produced by light of wavelength 514 nm, by what distance did one side of the object flex with respect to the other?

A student installs a double-slit assembly 1.55 m from a viewing screen. The slits are separated by 0.0574 mm. (a) Suppose the student directs a beam of yellow light, with a wavelength of 589 nm, toward the slit assembly, and this makes an interference pattern on the screen. What distance (in cm) separates the zeroth-order and first-order bright fringes (a.k.a. maxima)? cm (b) Now suppose that blue light (with 2= 414 nm) is used instead. What distance (in cm) will now separate the second-order and fourth-order bright fringes? cm
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.)
Light of wavelength 520 nm illuminates a slit of width 0.45 mm.

A single slit of width 4.50 x 10 ºm produces a first-order dark fringe at some angle. If the width of the slit is now changed to 3.08 × 10-ºm, a second-order dark fringe is found at three times the previous angle. What is the wavelength of the light?
