A diffraction grating with 345 lines/mm is 1.25 m in front of a screen. Part A What is the wavelength of light whose first-order maxima will be 16.4 cm from the central maximum on the screen? Express your answer to three significant figures. |IVE ΑΣΦ A= ? nm

Problem 2 Fringes are observed due to monochromatic light in a Michelson interfer- ometer. When the movable mirror is translated by 0.073 mm, a shift of 300 fringes is observed. What is the wavelength of the light? What displacement of the fringe system takes place when a flake of glass of index 1.51 and 0.005 mm thickness is placed in one arm of the interferometer? (Assume that the light beam is normal to the glass surface.)

Light of wavelength 690 nm falls on two slits and produces an interference pattern in which the fourth-order fringe is 37 mm from the central fringe on a screen 2.5 m away. Part A What is the separation of the two slits? Express your answer using two significant figures. ΑΣΦ d=270 10 6 = ?

When violet light of wavelength 415 nm falls on a single slit, it creates a central diffraction peak that is 9.20 cm wide on a screen that is 2.50 m away. Part A How wide is the slit? VE ΑΣΦ D = 7.14 Submit Previous Answers Request Answer X Incorrect; Try Again; 4 attempts remaining ? m

White light strikes a diffraction grating (625 lines/mm) at normal incidence. Part A What is the highest-order visible maximum that is formed? Express your answer to the nearest integer. |VLI ΑΣΦ m = 3 C ?

Two sources of electromagnetic waves (light waves) are emitting coherent waves at a frequency of 717 THz. These two sources are located a distance d apart and aimed at point A, as shown below. If the top source is located a distance 3.0 meters away from point A, find the minimum, nonzero, distance d that will give constructive interreference. Enter your answer in millimeters. 4₁ Laser Laser d A
