Image Formation Formula
The Formula
When to use: Your eye or a screen sees an image based on where the outgoing rays meet or appear to meet.
Quick Example
Notation
What This Formula Means
Image formation is the process by which reflected or refracted light creates an image that can be real or virtual, upright or inverted, magnified or.
Your eye or a screen sees an image based on where the outgoing rays meet or appear to meet.
Formal View
Common Mistakes
- Thinking virtual images are not real because they cannot be projected.
- Forgetting the sign of magnification when deciding whether an image is inverted.
Why This Formula Matters
Image formation ties together mirrors, lenses, cameras, eyes, telescopes, and microscopes in one school-level optics framework.

What do the symbols mean in the Image Formation formula?
h_o and h_i are object and image heights, d_o and d_i are distances, and m is magnification.
Why is the Image Formation formula important in Physics?
Image formation ties together mirrors, lenses, cameras, eyes, telescopes, and microscopes in one school-level optics framework.
What do students get wrong about Image Formation?
Real and virtual describe how rays behave, not whether the image is visible to your eye.
What should I learn before the Image Formation formula?
