Problem: The phase of reflection of electromagnetic waves depends on the polarization of the incident wave. Given the larger refractive index of the ground (typically n=2) compared to air (n=1), the phase of horizontally polarized radiation is reversed upon reflection (a phase shift of  radians or 180°). On the other hand, the vertical component of the wave's electric field is reflected at grazing angles of incidence approximately in phase. These phase shifts apply as well to a ground modelled as a good electrical conductor.
When is polarized radiation reversed?
The answer is the following: reflection

Problem: The peninsular borough's maritime heritage is acknowledged in several ways.The City Island Historical Society and Nautical Museum occupies a former public school designed by the New York City school system's turn-of-the-last-century master architect C. B. J. Snyder. The state's Maritime College in Fort Schuyler (on the southeastern shore) houses the Maritime Industry Museum. In addition, the Harlem River is reemerging as "Scullers' Row" due in large part to the efforts of the Bronx River Restoration Project, a joint public-private endeavor of the city's parks department. Canoeing and kayaking on the borough's namesake river have been promoted by the Bronx River Alliance. The river is also straddled by the New York Botanical Gardens, its neighbor, the Bronx Zoo, and a little further south, on the west shore, Bronx River Art Center.
What was the City Island Historical Society and Nautical Museum's building originally?
The answer is the following: a former public school

Problem: The CIPA DC-004 standard requires that Japanese manufacturers of digital still cameras use either the REI or SOS techniques, and DC-008 updates the Exif specification to differentiate between these values. Consequently, the three EI techniques carried over from ISO 12232:1998 are not widely used in recent camera models (approximately 2007 and later). As those earlier techniques did not allow for measurement from images produced with lossy compression, they cannot be used at all on cameras that produce images only in JPEG format.
With what cameras can earlier techniques not be used?
The answer is the following: cameras that produce images only in JPEG format

Problem: The textual critic's ultimate objective is the production of a "critical edition".[citation needed] This contains the text that the author has determined most closely approximates the original, and is accompanied by an apparatus criticus or critical apparatus. The critical apparatus presents the author's work in three parts: first, a list or description of the evidence that the editor used (names of manuscripts, or abbreviations called sigla); second, the editor's analysis of that evidence (sometimes a simple likelihood rating),[citation needed]; and third, a record of rejected variants of the text (often in order of preference).[citation needed]
What is included in the final part of the critical apparatus?
The answer is the following:
a record of rejected variants of the text (often in order of preference)
