APAKAH MAKSUD ELECTRON-VOLT dalam ROMANIA?
Elektronvolt
Pulse elektron digunakan dalam fizik nuklear dan kimia untuk menyatakan tenaga kinetik zarah subatomik serta tenaga yang diserap atau dilepaskan dalam reaksi nuklear atau kimia. Oleh kerana kesamaan jisim tenaga, denyut elektron boleh digunakan untuk menyatakan jisim: 1 eV / c ≈1,783 × 10-36 kg ≈1074 × 10-9 u dan ≈931,4 MeV Dalam tindak balas yang menghasilkan atau menyerap foton, antara tenaga foton dan panjang gelombang, di mana λ adalah panjang gelombang, ν adalah frekuensi sinaran, h ialah pemalar Plank dan c adalah kelajuan cahaya dalam vakum. Nilai hc yang dinyatakan dalam nanometer elektron-nanometer ialah: hc ^ 1240 eV · nm Dengan kata lain, foton 1 tenaga eV sepadan dengan panjang gelombang 1240 nm. Lampu kelihatan sesuai dengan foton dengan tenaga antara 1.77 eV hingga 3.1 eV.
