Bari mu yi ƙoƙari mu fahimta da misali

Abin da muke da shi:

- mita , wanda aka auna a cikin hertz (Hz), ainihinsa, a cikin sassauƙan kalmomi, sau nawa a cikin dakika nawa motsi yana faruwa. Misali, idan kun sami damar buga ganga a bugun 4 a sakan daya, hakan yana nufin kuna bugawa 4Hz.

– tsayin tsayi – madaidaicin mitar kuma yana ƙayyade tazara tsakanin oscillations. Akwai dangantaka tsakanin mita da tsawo, wato: mita = gudun/tsawon zango. A sakamakon haka, motsi tare da mitar 4 Hz zai sami tsawon zangon 1/4 = 0.25 m.

– kowane rubutu yana da nasa mitar

Ƙimar A (misali 8000A) ita ce naúrar ma'auni Angstrom.

1 angstrom = 1.0 × 10-10 mita = 0.1 nm = 100 na yamma

10000 Å = 1 µm

Ana yawan amfani da wannan naúrar ma'aunin a cikin ilimin kimiyyar lissafi, tunda 10-10 m shine madaidaicin radius na kewayawa na lantarki a cikin zarra na hydrogen mara daɗi. Ana auna launuka na bakan da ake gani a cikin dubban angstroms.
