Sura hii inaanzisha mawazo makuu ya optics ya kijiometri, ambayo yanaelezea malezi ya picha kutokana na kutafakari na kukataa. Inaitwa “kijiometri” optics kwa sababu picha zinaweza kutambuliwa kwa kutumia ujenzi wa kijiometri, kama vile michoro za ray. Tumeona kwamba mwanga unaoonekana ni wimbi la umeme; hata hivyo, asili yake ya wimbi inakuwa dhahiri tu wakati mwanga unapoingiliana na vitu vyenye vipimo vinavyolingana na wavelength (karibu 500 nm kwa mwanga unaoonekana). Kwa hiyo, sheria za optics za kijiometri zinatumika tu kwa kuingiliana kwa mwanga na vitu vingi zaidi kuliko wavelength ya mwanga.
