Intensity of Destructive Interference Calculator

Calculate Intensity of Destructive Interference





Formula

The formula to calculate the Resultant Intensity of Destructive Interference is:

\[ I_D = (\sqrt{I_1} - \sqrt{I_2})^2 \]

Where:

Definition

Resultant Intensity of Destructive Wave is the resulting intensity of a destructive wave that occurs when two or more waves overlap, causing a decrease in amplitude.

Example Calculation

Let's assume the following values:

Using the formula:

\[ I_D = (\sqrt{9} - \sqrt{18})^2 \]

Evaluating:

\[ I_D = 1.54415587728429 \text{ cd} \]

The Resultant Intensity of Destructive is 1.54415587728429 cd.
