Question: With nitrides containing aluminium, most often AlGaN and AlGaInN, even shorter wavelengths are achievable. Ultraviolet LEDs in a range of wavelengths are becoming available on the market. Near-UV emitters at wavelengths around 375395 nm are already cheap and often encountered, for example, as black light lamp replacements for inspection of anti-counterfeiting UV watermarks in some documents and paper currencies. Shorter-wavelength diodes, while substantially more expensive, are commercially available for wavelengths down to 240 nm. As the photosensitivity of microorganisms approximately matches the absorption spectrum of DNA, with a peak at about 260 nm, UV LED emitting at 250270 nm are to be expected in prospective disinfection and sterilization devices. Recent research has shown that commercially available UVA LEDs (365 nm) are already effective disinfection and sterilization devices. UV-C wavelengths were obtained in laboratories using aluminium nitride (210 nm), boron nitride (215 nm) and diamond (235 nm).
Try to answer this question if possible: What is the range of wavelengths for cheap UV LEEDs?
Answer: unanswerable

Question: Within the Indo-European language tree, Dutch is grouped within the Germanic languages, which means it shares a common ancestor with languages such as English, German, and Scandinavian languages. All Germanic languages are united by subjection to the sound shifts of Grimm's law and Verner's law which originated in the Proto-Germanic language and define the basic differentiating features from other Indo-European languages. This assumed to have originated in approximately the mid-first millennium BCE in Iron Age northern Europe.
Try to answer this question if possible: Along with Grimm's law, what's the other rule for Germanic-sounding speech called?
Answer: Verner's law
Question: During the Franco-Prussian War and the Siege of Strasbourg, the city was heavily bombarded by the Prussian army. The bombardment of the city was meant to break the morale of the people of Strasbourg. On 24 and 26 August 1870, the Museum of Fine Arts was destroyed by fire, as was the Municipal Library housed in the Gothic former Dominican church, with its unique collection of medieval manuscripts (most famously the Hortus deliciarum), rare Renaissance books, archeological finds and historical artifacts. The gothic cathedral was damaged as well as the medieval church of Temple Neuf, the theatre, the city hall, the court of justice and many houses. At the end of the siege 10,000 inhabitants were left without shelter; over 600 died, including 261 civilians, and 3200 were injured, including 1,100 civilians.
Try to answer this question if possible: What date was the Museum of Fine Arts destroyed by fire?
Answer:
24 and 26 August 1870
