For a convex lens, object placed at 2f forms image at:
AInfinity
Bf
C2f, same size, inverted, real
DBetween f and 2f
Answer & Solution
Correct answer: C. 2f, same size, inverted, real
**Convex lens with object at 2f:** image at 2f on other side, same size (|m|=1), inverted, real.
One of the standard imaging cases used in basic optics problems.
f-2f-2f-f rule of thumb.
