Mathematical Formulation
The relationship between the variables is governed by the following equation:
Variable Legend
| Symbol | Parameter | Unit |
|---|---|---|
| do | Object Distance (do) | cm |
| di | Image Distance (di) | cm |
Practical Calculation Example
Problem
Calculating the result when:
- Object Distance (do) = 40 cm
- Image Distance (di) = 90 cm
Solution
Substituting into Eq 1.1:
Result = 1 ÷ ((1÷40) + (1÷90))
