Thin lens equation relates object distance, image distance, and focal length. It's fundamental to cameras, microscopes, telescopes, and corrective lenses.

The calculator applies 1/f = 1/s_o + 1/s_i
f
1/s_o + 1/s_i — 1/s_o + 1/s_i

  • Confusing sign conventions for distances and focal lengths
  • Using lens equations without considering real vs. virtual images

ବାରମ୍ବାର ଜିଜ୍ଞାସା

When do you get virtual images?

Virtual images form when the object is closer than the focal point (s_o < f); the image appears upright and magnified.

What's the difference between converging and diverging lenses?

Converging (convex) lenses have positive focal length and form real images; diverging (concave) lenses have negative focal length and only form virtual images.
