Calculate Reflectance



Formula

The formula to calculate the Reflectance (R) is:

\[ R = \left( \frac{RR}{IR} \right)^2 \]

Where:

Example

Let's say the reflected radiation (RR) is 50 and the incident radiation (IR) is 100. Using the formula:

\[ R = \left( \frac{50}{100} \right)^2 \]

We get:

\[ R = 0.25 \]

So, the reflectance is 0.25.
