Theory & Logic
Theoretical Background
Physics describes the fundamental mechanism of the universe. The Mirror Equation is an essential tool for understanding Mirror Equation in quantitative terms. Calculate focal length f = (do*di)/(do+di).
Mathematical Formulation
The relationship between the variables is governed by the following equation:
Variable Legend
| Symbol | Parameter | Unit |
|---|---|---|
| do | Object Dist | cm |
| di | Image Dist | cm |
Practical Calculation Example
Problem
Calculating the result when:
- Object Dist = 100 cm
- Image Dist = 95 cm
Solution
Substituting into Eq 1.1:
Result = (100 × 95) ÷ (100 + 95)
