Calculate Inverse Square Law







Formula

The formula to calculate the inverse square law is:

\[ \frac{I1}{I2} = \frac{D2^2}{D1^2} \]

What is the Inverse Square Law?

The inverse square law states that any physical quantity is proportional to the square of the distance from the source of the physical entity. It is commonly used in physics to describe the intensity of radiation, sound, and other phenomena.

Example Calculation

Let's assume the following values:

Using the formula to calculate the final radiation:

\[ \frac{I1}{I2} = \frac{D2^2}{D1^2} \implies I2 = I1 \times \left(\frac{D1}{D2}\right)^2 = 100 \times \left(\frac{2}{4}\right)^2 = 25 \text{ units} \]

The final radiation (I2) is 25 units.
