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?
Answer to relevant Questions(a) Only a limited number of maxima can be observed with a diffraction grating. The factor(s) that limit(s) the number of maxima seen is (are) (a) (1) the wave-length, (2) the grating spacing, (3) both. Explain. (b) How ...White light of wavelength ranging from 400 nm to 700 nm is used for a diffraction grating with 6500 lines per centimeter. (a) In a particular order of maximum, red color will have (1) a larger, (2) the same, or (3) a ...Light is incident on a certain material in air. (a) If the index of refraction of the material increases, the polarizing (Brewster) angle will (1) also increase, (2) decrease, (3) remain the same. Explain. (b) What are the ...Sunlight is reflected off a vertical plate-glass window (n = 1.55). What would the Sun’s altitude (angle above the horizon) have to be for the reflected light to be completely polarized? The critical angle for a certain plastic and air interface is 39o. If the angle of incidence is adjusted so the reflected light has maximum polarization, what would be the angle of refraction?
