Formula and methodology
Formula: New value=initial value×(initial distance/new distance)².
The distance scaling is explicit and does not identify what physical source or safety threshold the value represents.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Initial field or intensity — minimum 0; maximum 1000000000000
- Initial distance — minimum 1.0E-6; maximum 1000000000
- New distance — minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Initial field or intensity | 100 |
| Initial distance | 2 |
| New distance | 4 |
New value =25.
Assumptions and limits
- Distances use one unit and value is measured consistently at both points.
- The source is point-like and unobstructed with inverse-square geometry.
- Absorption, reflection, near-field effects, shielding, and safety limits are not modeled.
