A chamber 5.0 cm long with flat, parallel windows at the ends is placed in one arm of a Michelson interferometer (see below). The light used has a wavelength of 500 nm in a vacuum. While all the air is being pumped out of the chamber, 29 fringes pass by a point on the observation screen. What is the refractive index of the air?
Consider a diffraction grating with a grating constant of 500 lines/mm. The grading is illuminated with a composite light source consisting of two distinct wavelengths of light being 666 nm and 501 nm. If a screen is placed a distance of 57 m away, what is the linear separation between the 1st order maxima of the 2 wavelengths? Express this distance in meters.
Recall from class that the resolution is limited due to the nature of light. More specifically, since light diffracts as it goes through a small opening, it becomes difficult to differentiate two light sources when the diffraction central peak from one source overlaps with the first minimum of the second source, as shown in the figure below. (a) The pupil of the human eye has an aperture of around 5mm, and visible light has wavelengths peaked around 500nm. Estimate the angular resolution of the human eye (that is, the smallest angle for which you could distinguish that light was coming from two different directions). (b) Suppose two point sources of light were separated by a distance x, and you are standing one meter away from them. Estimate the smallest distance x for which you could tell that there were two point sources (rather than just one).

Three monochromatic (single color) light sources are each passed through a mask with a single pinhole. All of the pinholes are exactly the same size. Each mask is the same distance from a screen, where the diffraction patterns are observed. Which light source produces the largest central bright spot on the screen?
You set up four two slit interference experiments (A-D), each using an identical laser as the lightsource. Each experiment uses a different mask containing two slits.

This question is regarding the experiment ’Diffraction and Interference of Light’. a) In a diffraction experiment for a given slit and a given slit-screen distance,would the distance between the dark fringes increase or decrease when a blue laser is replaced with a red laser? Use equations to argue why, in no more than two sentences (Hint: wavelength λblue = 470nm, λred = 700 b) Draw the pattern you observe for two slit interference. Mark clearly the diffraction and the interference parts of this pattern. c) How will the pattern change? When I change the distance between the slits?
