What is the lens and mirror equation
If u = object distance, v = image distance, & f = focal length of a mirror or of a thin lens, the equation is 1/v + 1/u = 1/f. Read More »

What is lens makers equation ?
the full statement of the lens maker's equation is: 1/f = (n-1)[1/R1 - 1/R2 + (n-1)d/(n R1 R2)] where f is the focal length n is the index of refraction of the glass R1, R2 are the radii of curvature of the two sides of the lens d is the th... Read More »

What would lenses for a 120film camera equate to in the 35mm film...
The focal length would roughly double. For example, if you have a 60mm lens for a Hasselblad, and managed to hack it to fit a 35mm camera, that same 60mm lens would be roughly 120mm in a 35mm camera. Read More »

1 / do = 1 / f - 1 / di 1 / do = (di - f) / (f * di) do = (f * di) / (di - f). 1 / di = 1 / f - 1 / do 1 / di = (do - f) / (f * do) di = (f * do) / (do - f).

I should take some time to introduce the concept of "paraxial optics," or "first-order optics." Paraxial optics means that we trace rays which never deviate more than infinitesmally from the optical axis, but generalize the trace to all fie...

the mirror equation is 1/v - 1/u = 1/f lens equation is 1/v+1/u=1/f where v=image distance u=object distance f= focal length 'u' is always negative no matter what 'v' and 'f' signs depend on the type of mirror or lens distances taken on rig...
