Calculate Resultant Intensity





Formula

The formula to calculate the Resultant Intensity is:

\[ I = 4 \cdot I_{S1} \cdot \cos^2\left(\frac{\Phi}{2}\right) \]

Where:

Definition

Resultant Intensity is the intensity of the resulting wave pattern formed by the superposition of two or more waves, providing information about the combined effect of the individual waves.

Example Calculation

Let's assume the following values:

Using the formula:

\[ I = 4 \cdot 13.162 \cdot \cos^2\left(\frac{0.67195176201769}{2}\right) \]

Evaluating:

\[ I = 46.925377120985 \text{ Candela} \]

The Resultant Intensity is 46.925377120985 Candela.
