A combined beam of equal amounts purple (lambda = 400 nm) and orange (lambda = 600 nm) light is incident on a thin film (n =3/2, thickness t = 100 nm) with air on both sides. Assume the extra distance traveled is just 2t (tiny incident angle). Due to interference, the reflected light appears to be ______ (a) entirely purple (b) entirely orange (c) more purple than orange (d) more orange than purple (e) equally orange and purple (both reflected perfectly) (f) equally orange and purple (both diminished, but equally)

Consider a single-slit diffraction pattern for =589 nm, projected on a screen that is 1.00 m from a slit of width 0.25 mm. How far from the center of the pattern are the centers of the first and second dark fringes?
For 600-nm wavelength light and a slit separation of 0.12 mm, what are the angular positions of the first and third maxima in the double slit interference pattern?
In an experiment, green light with wavelength 520 nm, sent through a pair of slits 32.5 µm apart, produces bright fringes 1.92 cm apart on a screen 1.20 m away. If the apparatus is now submerged in a tank containing a sugar solution with index of refraction 1.38, calculate the fringe separation for this same arrangement.
White light is incident normally on a glass lens (n=1.52) that is coated with a film of MgF2(n=1.38). For what minimum thickness of the film will the reflections at the two interfacesresult in total destructive interference of yellow light of wavelength 580 nm (in air)?
Sound waves with frequency 4000 Hz and speed 350 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 31.0 cm, faces a wall 100 m away. Along that wall, how far from the central axis will a listener be at the first diffraction minimum and thus have difficulty hearing the sound?
Both sides of a uniform film that has index of refraction n and thickness d are in contact with air. For normal incidence of light, an intensity minimum is observed in the reflected light at λ2 and an intensity maximum is observedat λ1, where λ1> λ2. (a) Assuming no intensity minima are observed between λ1 and λ2, find an expression for the integer m in as shown in terms of the wavelengths λ1 and λ2. (b) Assuming n = 1.40, λ1 = 500 nm, and λ2 = 370 nm, determine the best estimate for the thickness of the film.

Suppose you're shining a light through a small slit (width=400 nm). Which will diffract more: a red laser with a wavelength of 650 MLM or a green laser with a wavelength of 450 nm?
A beam of light with wavelength 440 nm in air hits a thin piece of glass 10.28 microns thick (with refractive index 1.55) at an angle of 40.8 degrees to the normal. What is the path difference between the two reflections from the layers of the glass, in wavelengths? [Note to get the phase shift we multiply this number by 2π, but this is modulo 2π, i.e. any integer number of wavelengths are 2π phase shifts, equivalent to no phase shift... basically in terms of phase we only really need the non-integer part of your answer. Note also that for the phase shift we would need to add a π for the reflection off the glass-air interface.]
