Resultant Intensity On-Screen of Young's Double-Slit Experiment Calculator

Formula

The formula to calculate the Resultant Intensity is:

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

Where:

\(I\) is the Resultant Intensity (Candela)
\(I_{S1}\) is the Intensity from Slit 1 (Candela)
\(\Phi\) is the Phase Difference (Radian)

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:

Intensity from Slit 1 (\(I_{S1}\)) = 13.162 Candela
Phase Difference (\(\Phi\)) = 0.67195176201769 Radian

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.
