How does getting closer to a light source affect the amount of light received?

When you get closer to a light source, the intensity of light you receive increases, and this is governed by the Inverse Square Law. This law states that the intensity of light (or other forms of radiation) from a point source is inversely proportional to the square of the distance from the source.

As you decrease your distance to the light source, the same amount of light radiates over a smaller area, resulting in a higher intensity. Therefore, if you halve the distance to the source, you effectively quadruple the amount of light received because the intensity increases as the inverse of the square of the distance.

For example, if you are initially 2 meters away from the source and then move to 1 meter, the amount of light you receive increases by a factor of four. This principle explains why closer proximity to a light source results in a significantly increased amount of light received.
