∆What is the Inverse Square Law Formula?
The intensity of the light to an observer from a source is inversely proportional to the square of the distance from the observer to the source. This shows that as the distance from a light source increases, the intensity of light is equal to a value multiplied by 1/d2. Thus closer a light source brighter it is. This is very evident from the fact that in the night when a car approaches us from a distance it looks dark but as it comes near the light the headlights make it be brighter as the distance between the observer and the car has decreased.
