Q. A square aperture of 0.3 mm size is illuminated with light from a He-Ne laser (632 nm wavelength). A convex lens of 1 m focal length projects a Fraunhofer diffraction pattern on the screen placed at the lens's focal plane. Find the relative intensity of the light (compared to the center) at a point 3 mm diagonally from both the Y and Z axes.

Mirror M₁ in the figure below is moved through a displacement AL. During this displacement, 248 fringe reversals (formation of successive dark or bright bands) are counted. The light being used has a wavelength of 631.4 nm. Calculate the displacement AL. μm A single ray of light is split into two rays by mirror Mo, which is called a beam splitter. Telescope As M₁ is moved, an interference pattern changes in the field of view. Light source L₂ M₂ Mo 4₁ The path difference between the two rays is varied with the adjustable mirror M₁. M₁
The Michelson interferometer can be used to measure the index of refraction of a gas by placing an evacuated transparent tube in the light path along one arm of the device. Fringe shifts occur as the gas is slowly added to the tube. Assume 580-nm light is used, the tube is 5.40 cm long, and 152 fringe shifts occur as the pressure of the gas in the tube increases to atmospheric pressure. What is the index of refraction of the gas? Hint: The fringe shifts occur because the wavelength of the light changes inside the gas-filled tube. (Give your answer to five decimal places.) 4.0
4. a. Determine the size of the Airy disk (in m) found at the center of a 4.00-cm diameter lens, with a focal length of 15.0 cm. Assume the incident light wavelength is the middle of the visible spectrum = 550. nm. b. In observational astronomy, we assume that stars, being so far away, are point sources of light, and that the image of a star in a telescope eyepiece is therefore also a point. Given that the average human near-field resolution is 0.10 mm, does your result in part a justify this assumption? Explain your answer, using the value from part a. c. Assume that the objective lens diffraction limit is the only one that matters on a telescope (actually a good assumption, not justified here).
