Kufananidzwa kwemavara epurasitiki kunobva pamavara matatu ekutanga ered, yero uye yebhuruu, kuti aenderane nemuvara une mukurumbira, unosangana nezvinodiwa nemusiyano weruvara rwekadhi reruvara, ine mari, uye haichinji ruvara panguva yekugadziriswa nekushandisa.Mukuwedzera, ruvara rwepurasitiki runogonawo kupa mabasa akasiyana-siyana kumapurasitiki, akadai sekuvandudza chiedza chekudzivirira uye kuramba kwemamiriro ekunze emapurasitiki;kupa mapurasitiki mamwe mabasa anokosha, akadai semagetsi conductivity uye antistatic properties;akasiyana mavara ekurima mulch mafirimu ane mabasa ekusakura kana kudzinga zvipembenene uye kurera mbesa.Kureva kuti, inogona zvakare kusangana nezvimwe zvinodiwa zvekushandisa kuburikidza nekuenzanisa kwemavara.
Nekuda kwekuti ruvara rwakanyanya kutarisisa kumamiriro ekugadzirisa epurasitiki, chimwe chinhu mukugadzirisa kwepurasitiki kwakasiyana, senge zvakasarudzwa zvigadzirwa, toner, muchina, maparamita ekuumba uye mashandiro evashandi, nezvimwewo, pachave nekusiyana kwemavara.Naizvozvo, kuenzanisa kwemavara ibasa rinoshanda kwazvo.Kazhinji, isu tinofanirwa kutarisisa kune pfupiso uye kuunganidzwa kwechiitiko, uye tozobatanidza dzidziso yehunyanzvi yepurasitiki ruvara rwekuenzanisa kukurumidza kuvandudza tekinoroji yekufananidza ruvara.
Kana iwe uchida kupedzisa kuwirirana kwemavara zvakanaka, unofanira kutanga wanzwisisa musimboti wekugadzirwa kwemavara uye kufananidzwa kwemavara, uye zvichibva pane izvi, unogona kuva nekunzwisisa kwakadzama kweruzivo rwakarongeka rwepurasitiki ruvara rwekufananidza.
Pakupera kwezana remakore rechi17, Newton akaratidza kuti ruvara haruna muchinhu chacho, asi mugumisiro wekuita kwechiedza.Newton anodzora chiedza chezuva kuburikidza neprism obva azvigadzira pachikirini chichena, chinozoratidza bhendi reruvara rwakanaka semurarabungu (mavara manomwe ered, orenji, yero, girini, cyan, bhuruu, nepepuru).Masaisai emwenje marefu uye mapfupi pane inooneka spectrum anobatana kuita chiedza chichena.
Saka, ruvara chikamu chechiedza uye chinoumbwa nemasaisai emagetsi ehurefu hwakasiyana siyana.Kana masaisai echiedza achiratidzwa pachinhu, chinhu chacho chinofambisa, chinotora kana kuratidza zvikamu zvakasiyana zvemasaisai echiedza.Apo aya masaisai anoratidzirwa ourefu hwakasiana anonyandura meso avanhu, anobudisa mavara akasiana-siana muuropi hwomunhu, uye ndiwo mauyiro anoita mavara.
Iko kunonzi kuenderana kwemavara ndeyekuvimba neiyo theoretical hwaro hwematatu ekutanga mavara, uye kushandisa hunyanzvi hwekuwedzera ruvara, inobvisa ruvara, kuenzanisa kwemavara, inopindirana ruvara uye achromatic ruvara kugadzirira chero ruvara rwakatarwa rwunodiwa nechigadzirwa.
