Paano Kalkulahin si Thin Lens
Ano ang Thin Lens?
Thin lens equation relates object distance, image distance, and focal length. It's fundamental to cameras, microscopes, telescopes, and corrective lenses.
Pormula
The calculator applies 1/f = 1/s_o + 1/s_i
- f
- 1/s_o + 1/s_i — 1/s_o + 1/s_i
Step-by-Step na Gabay
- 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
Mga Nalutas na Halimbawa
Input
s_o = 30 cm, f = 10 cm
Resulta
s_i = 15 cm, magnification = 0.5×
Real inverted image
Mga Karaniwang Mali na Dapat Iwasan
- ✕Confusing sign conventions for distances and focal lengths
- ✕Using lens equations without considering real vs. virtual images
Mga madalas itanong
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.
