Thin Lens کا حساب کیسے لگائیں
Thin Lens کیا ہے؟
Thin lens equation relates object distance, image distance, and focal length. It's fundamental to cameras, microscopes, telescopes, and corrective lenses.
فارمولا
The calculator applies 1/f = 1/s_o + 1/s_i
- f
- 1/s_o + 1/s_i — 1/s_o + 1/s_i
مرحلہ وار گائیڈ
- 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

عام غلطیاں جن سے بچنا ہے
- ✕Confusing sign conventions for distances and focal lengths
- ✕Using lens equations without considering real vs. virtual images
اکثر پوچھے جانے والے سوالات
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.
