Interference of Waves of Two Intensities Calculator

Calculate Interference of Waves of Two Intensities







Formula

The formula to calculate the Resultant Intensity is:

\[ I = I_1 + I_2 + 2 \sqrt{I_1 I_2} \cos(\Phi) \]

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:

\[ I = 9 + 18 + 2 \sqrt{9 \cdot 18} \cos(0.67195176201769) \]

Evaluating:

\[ I = 46.9219512500029 \text{ cd} \]

The Resultant Intensity is 46.9219512500029 cd.
