Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Crookes akagadzira maTubes aCrookes, achiongorora mwaranzi dzecathode. Akabudisa mapepa akawanda pamusoro pe spectroscopy uye akaitisa tsvakurudzo pamhando dzakasiyana-siyana dzenyaya duku. Mukuongorora kwake kutungamirirwa kwemagetsi mumagasi ane dzvinyiriro yakaderera, akawana kuti sezvo dzvinyiriro yakaderedzwa, electrode yakaipa (cathode) yakaoneka kuti inoburitsa mwaranzi (inonzi "mwenje ye cathode", zvino inozivikanwa kuva rwizi rwemaerekitironi akasununguka, uye inoshandiswa mumidziyo inoratidza mwaranzi ye cathode). Sezvinoratidzwa nemienzaniso iyi, aiva piyona pakuvaka uye kushandisa zvitubu zvisina chinhu pakudzidza nezvezvinhu zvinooneka. Somugumisiro, akanga ari mumwe wevasayendisiti vokutanga kuongorora icho zvino chinonzi plasma ndokuchizivisa sorudzi rwechina rwezvinhu muna 1879. Akagadzirawo chimwe chezviridzwa zvokutanga zvokudzidza radioactivity yenyukireya, spinthariscope.  Mubvunzo: Chii chaakasika kuti abatsire kudzidza radioactivity yenyukireya?
spinthariscope
