Question
as you move farther and farther away from a light source, the luminous intensity: stays the same increases decreases rewatch
The inverse - square law in physics states that the luminous intensity (or illuminance) of a light source is inversely proportional to the square of the distance from the source. Mathematically, \(E=\frac{I}{d^{2}}\) (where \(E\) is illuminance, \(I\) is luminous intensity of the source, and \(d\) is the distance from the source). As \(d\) (distance) increases, \(E\) (the amount of light per unit area, which is related to our perception of brightness) decreases.
