Ray Diagram of Thin Convex Lens

Enter 2 distances (f,u,v) and 1 height (h1,h2) to calculate the 3rd distance and 2nd height. Distances are measured from the optical centre of lens. To standardize enter only positive values for f,u and h1 so object is always real and upright. If you enter v and h2 together, make sure both have the same sign, either positive or negative. If both height fields are left blank then object height will be set to a default value of 10cm.

Focal Length f (cm):
Object Dist u (cm):
Image Dist v (cm):
Object Height h1 (cm):
Image Height h2 (cm):

Move object freely by dragging it yourself

Focal length f and object height h1 are both set to 10cm. The rest changes according to how you drag the object.
