I know that the answer to the question "Which is smaller, human eyes or photons?" is in "Equivalently, the smallness of the Planck constant reflects the fact that everyday objects and systems are made of a large number of particles. For example, green light with a wavelength of 555 nanometres (the approximate wavelength to which human eyes are most sensitive) has a frequency of 7014540000000000000♠️540 THz (7014540000000000000♠️5401012 Hz). Each photon has an energy E = hf = 6981358000000000000♠️3.581019 J. That is a very small amount of energy in terms of everyday experience, but everyday experience is not concerned with individual photons any more than with individual atoms or molecules. An amount of light compatible with everyday experience is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, NA 7023602200000000000♠️6.0221023 mol1. The result is that green light of wavelength 555 nm has an energy of 7005216000000000000♠️216 kJ/mol, a typical energy of everyday life.". Can you tell me what it is?

I know that the answer to the question "The English word Geography can be translated to Latin as?" is in "The Tibetan name for their land, Bod , means "Tibet" or "Tibetan Plateau", although it originally meant the central region around Lhasa, now known in Tibetan as U. The Standard Tibetan pronunciation of Bod, [p], is transcribed Bho in Tournadre Phonetic Transcription, Bo in the THL Simplified Phonetic Transcription and Poi in Tibetan pinyin. Some scholars believe the first written reference to Bod "Tibet" was the ancient Bautai people recorded in the Egyptian Greek works Periplus of the Erythraean Sea (1st century CE) and Geographia (Ptolemy, 2nd century CE), itself from the Sanskrit form Bhautta of the Indian geographical tradition.". Can you tell me what it is?

I know that the answer to the question "What changed about schooling" is in "Finland has used comprehensive schools since the 1970s, in the sense that everyone is expected to complete the nine grades of peruskoulu, from the age 7 to 16. The division to lower comprehensive school (grades 16, ala-aste, alakoulu) and upper comprehensive school (grades 79, ylaaste, ylakoulu) has been discontinued.". Can you tell me what it is?
