The "cloak" scientists have invented
(26) Scientists have created the first device to render an object invisible in three dimensions. The "cloak" hid an object from detection using light of wavelengths close to those that are visible to humans. Previous devices have been able to hide objects from light traveling in only one direction; viewed from any other angle, the object would remain visible. This is a very early but significant step towards true invisibility cloaks.
选项
A、can keep an object invisible in three dimensions.
B、can hide an object from detection only in one direction.
C、is a true invisibility cloak.
D、is just a minor achievement.
