PHY 物理 virtual 同real image 問題

The image formed on the photographic film in a camera is ALWAYS real

呢句statement係real

佢用always呢個字...咁係咪o者係the image formed on the photographic film in a camera 係咪係可以唔係REAL IMAGE?IF YES, 咁可以係咩IMAGE?

同埋...我想問

The image formed on the photographic film 等唔等於 formed on the screen個個原理?

thanks!!!!!!
