Часті запитання

What is the thin lens equation?

1/f = 1/do + 1/di, where f is the focal length, do is the object distance from the lens, and di is the image distance from the lens.

How is magnification calculated for a thin lens?

Magnification is calculated as m = -di/do, where a negative value indicates an inverted image and a positive value indicates an upright image.
