Suppose a double-slit interference pattern has its third minimum at an angle of 0.281° with slits that are separated by 327 μm. a) Calculate the wavelength of the light in nm.

Given a double slit set up with a spacing of 5.74*10-6m and the light has a wavelength of 618 nm: How far from the central maximum is the third dark fringe (m=2) when the distance between the slits and the screen is 5.00 meters? a) 1.40m b) 2.03m c) 1.30m d) 1.10m (Hint: answer is a)

A light with wavelength λ = 565 nm falls on a pair of closely separated slits. The first dark fringe of the interference pattern is at an angle θ = 3.25 degrees from the central maximum. a) Solve for the numerical value of d in mm.

The central bright fringe in a single-slit diffraction pattern from light of wavelength 518 nm is 2.00 cm wide on a screen that is 1.05 m from the slit. A) How wide is the slit? B) How wide are the first two bright fringes on either side of the central bright fringe?

33. You have a laser (a monochromatic light source) and want to estimate the wavelength. You decide to use a reflective diffraction grating to do this. The light is incident on the grating at 20 degrees with respect to normal. Using a grating with a groove distance of 5 um, the first-order diffraction, is found at an angle of -12.5 degrees. Determine the wavelength of the source. a) 500 nm b) 628 nm c) 808 nm d) 946 nm e) None of the above 34. In Raman spectrometry, Stokes lines have a) lower energy than that of anti-Stokes scattering. b) equal energy to that of anti-Stokes scattering. ) higher energy than that of anti-Stokes scattering d) none of the above 35. Upon ionization of phenol in aqueous solution, maximal UV absorbance changes to longer wavelength. a) True b) False 36. It takes longer time to observe fluorescence than phosphorescence. a) True b) False 37. The vibrational motion of C-H stretching in ethylene as in the figure can be detected by a) IR. b) Raman. c) IR and Raman.…

Light of wavelength 575 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle of 13.0° from the central maximum. Find the separation between the slits. μm

A double-slit experiment has a slit separation distance of 0.08 mm.  If the bright interference fringes are to be spaced 5 mm apart on the screen when the slits are illuminated with a laser of wavelength 633 nm, what should be the distance to the screen from the slits? a) 0.42 m b) 0.63 m c) 0.77 m d) 0.81 m e) 0.92 m

b. Coherent light of wavelength 590 nm passes through a thin single slit and a diffraction pattern is observed at a screen 1.5 m from the slits. The first dark fringe is observed at 2.00 mm from the center (i) What is the width of the slit? (ii) What is the location of the next symmetrical pair of dark fringes from the centre?

a) At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00 um? When i solve the question, there is no way i get the answer to be 33.4 deg. rather i get the sin-1 (0.55) = 0.58. IS the final answer wrong in the bartley and the test book or am i wrong?

A double slit experiment using 532 nm light produces an interference pattern with the 1st order maxima separated by an angle of 0.115° from the central maxima. At what distance away should a viewing screen be placed such that the 1st and 2nd order maxima are separated by 6.00 mm?
