The Significance of Total Intensity
In technical phrases, overall depth (I) may be defined as:
I(θ) = dE/dΩ
Where:
- dE = differential electricity emitted
- dΩ = differential strong angle (in steradians)
This system indicates that the full depth is a characteristic of the electricity emitted consistent with unit strong attitude. When an observer or sensor evaluates the emitted electricity at different angles, I(θ) changes, indicating how energy propagates via area.
