Find the angles of the blue (λ = 420nm) and red components of the first-and second-order maxima in a pattern produced by a diffraction grating with 7500 lines/cm.
Answer to relevant QuestionsA 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? The commonly used CD (Compact Disc) consists of many closely spaced tracks that can be used as reflecting gratings. The industry standard for the track-to-track distance is 1.6μm. If a He–Ne laser with a wavelength of ...Some types of glass have a range of indices of refraction of about 1.4 to 1.7. What is the range of the polarizing (Brewster) angle for these glasses when light is incident on them from air? (a) The polarizing (Brewster) angle of a piece of flint glass (n = 1.66) in water is (1) greater than, (2) less than, (3) the same as that of the glass in air. Explain. (b) What are the polarizing angles when it is in air ...Show that when the reflected light is completely polarized, the sum of the angle of incidence and the angle of refraction is equal to 90o.
