Spherical mirror image distance & magnification.
Category: Geometric Optics
Formula: 1/f = 1/do + 1/di
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Radius R | R | mm | 200 |
| Object dist | do | mm | 300 |
Result with the default inputs
- Focal length: 100 mm
- Image dist: 150 mm
- Magnification: -0.5×
Open it with your own values: put each input in the address as a parameter, for example /calculators/mirror-equation?R=200. A unit other than the listed one goes in <parameter>_unit.
