Optica geometrică. 9

Optica geometrică

În medii omegene și transparente, lumina se propagă rectiliniu
La reflexie, lumina în mediul din care vine se returnează
Unghiul de reflexie și unghiul de incidență sunt egale
Imaginea unui obiect în oglinda plană este virtuală
În oglinda plană, imagginea și obiectul sunt ...... față de oglindă simetrice
Dispozitivul de observare a câmpului de acțiune, care utilizează reflexia luminii, se numește periscop
