Thin lens equation relates object distance, image distance, and focal length. It's fundamental to cameras, microscopes, telescopes, and corrective lenses.
सूत्र
The calculator applies 1/f = 1/s_o + 1/s_i
- f
- 1/s_o + 1/s_i — 1/s_o + 1/s_i
चरण-दर-चरण मार्गदर्शिका
- 1Enter any two of: object distance (s_o), image distance (s_i), or focal length (f)
- 2The calculator applies 1/f = 1/s_o + 1/s_i
- 3Results show lens behavior and image characteristics

सामान्य गलतियां जिनसे बचना है
- ✕Confusing sign conventions for distances and focal lengths
- ✕Using lens equations without considering real vs. virtual images
अक्सर पूछे जाने वाले प्रश्न
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.
