Convex Lens Image Formation

Explore how a convex lens forms images. Adjust the object distance and focal length to see how real and virtual images are created. Observe the three principal rays in 3D space.

Variables

20.0 cm
10.0 cm

Real-time Data

Image Dist. ($v$) 20.00 cm
Magnification ($m$) -1.00
Type Real, Inverted

Lens Formula

$$ \frac{1}{f} = \frac{1}{u} + \frac{1}{v} $$
$$ m = -\frac{v}{u} $$

Sign Convention: Real is positive (Cartesian).
