In the development of Young’s double-slit experiment, a small-angle approximation (tan θ ≈ sin θ) was used to find the lateral displacements of the maxima (bright) and minima (dark) positions. How good is this approximation? For example, what is the percentage error for θ = 10o?
Answer to relevant QuestionsA film on a lens with an index of refraction of 1.5 is 1.0 x 10-7 m thick and is illuminated with white light. The index of refraction of the film is 1.4. (a) The number of waves that experience the phase shift is (1) zero, ...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 ...A venetian blind is essentially a diffraction grating—not for visible light, but for waves with much longer wave-lengths. If the spacing between the slats of a blind is 2.5 cm, (a) For what wavelength would there be a ...A diffraction grating with is illuminated with a red light from a He– Ne laser (λ = 632.8 nm). How many side maxima are formed in the diffraction pattern, and at what angles are they observed? When un polarized light is incident on a polarizer–analyzer pair, 30% of the original light intensity passes the analyzer. What is the angle between the transmission axes of the polarizer and analyzer?
