The formula to calculate Optical Distance (D) is:
\[ D = \sqrt{\frac{Q}{E}} \]
Where:
Optical distance refers to the distance at which a certain quantity of light, measured in lumens, can be perceived at a given light intensity, measured in lumens per square meter. This calculation is important for understanding how far light can travel and still be effective for illumination purposes.
Let's assume the following values:
Using the formula to calculate Optical Distance:
\[ D = \sqrt{\frac{1000}{50}} = \sqrt{20} \approx 4.47 \text{ meters} \]
The Optical Distance (D) is approximately 4.47 meters.
