Question: The glass plates in Fig 24 30 are separated by a
The glass plates in Fig. 24.30 are separated by a thin, round filament. When the top plate is illuminated normally with light of wavelength 550 nm, the filament lies directly below the sixth maximum (bright) position. What is the diameter of the filament?
Relevant QuestionsA slit of width 0.15 mm is illuminated with monochromatic light of wavelength 632.8 nm. At what angle will the first minimum occur? At what angle will the second-order maximum be seen from a diffraction grating of spacing 1.25 μm when illuminated by light of wavelength 550 nm? A certain crystal gives a deflection angle of 25o for the first-order maximum of monochromatic X-rays with a frequency of 5.0 x 1017 Hz. What is the lattice spacing of the crystal? White light whose components have wavelengths from 400 nm to 700 nm illuminates a diffraction grating with 4000 lines/cm. Do the first-and second-order spectra overlap? Justify your answer. The critical angle for total internal reflection in a certain media boundary is 45o. What is the polarizing (Brewster) angle for light externally incident on the same boundary?
