Intensity of Constructive Interference Calculator

Calculate Intensity of Constructive Interference





Formula

The formula to calculate the Intensity of Constructive Interference is:

\[ I_C = \left( \sqrt{I_1} + \sqrt{I_2} \right)^2 \]

Where:

Definition

Resultant Intensity of Constructive Interference is the combined intensity of two or more waves that are in phase with each other, resulting in a wave with increased amplitude.

Example Calculation

Let's assume the following values:

Using the formula:

\[ I_C = \left( \sqrt{9} + \sqrt{18} \right)^2 \]

Evaluating:

\[ I_C = 52.4558441227157 \text{ cd} \]

The Resultant Intensity of Constructive Interference is 52.4558441227157 cd.
