It's what we call constructive interference, or destructive interference... so that the light from two or more telescopes... can produce a brighter image than one alone.
Eshte pikerisht ajo qe quajme interference konstruktive, ose interference destruktve... keshtu qe drita nga 2 ose me shume teleskope... mund te prodhoje, um, uh, nje imazh me te ndritshem sesa nga nje i vetem.
