Which one of the below statements is wrong?    Select one: Color dispersion in a dielectric material is an indication of the frequency dependence of its refractive index. A spherical ball of glass (ng = 1.5), with a radius of 20 cm, is immersed in water (nw = 1.3). The surface of the ball has a refractive power of 0.01 D. Fermat’s principle states that the trajectory of a light ray between two points extremizes the total optical path.
You are working for an electronics company that designs and manufactures digital drives and players. Your supervisor wishes to evaluate the feasibility of using shorter-wavelength lasers than those used in Blu-ray Discs (405 nm) to try to begin a new video revolution with Ultraviolet-ray discs. as  shown the general idea behind digital reading of CDs, DVDs, and Blu-ray Discs. The information is coded digitally in a plastic substrate of index of refraction 1.78 (green as shown). as  shown areas called flats, which are undisturbed portions of the substrate, and pits, which are depressions in the substrate that represent the digital information. The surface of the substrate is covered with a protective reflective coating (as shown) to protect the surface from scratches. As the disc rotates, the laser beam, shown in violet coming in from below the disc, passes over a track of flats and pits. When there is a change from a flat to a pit or vice versa, part of the laser beam reflects from the…
In the figure, first-order reflection from the reflection planes shown occurs when an x-ray beam of wavelength 0.820 nm makes an angle θ = 62.3˚ with the top face of the crystal. What is the unit cell size a0?
