Unfortunately, we have to start the discussion with science.

The inverse square law of light states that the intensity of light from a point source decreases in proportion to the square of the distance from the source.

This means that if you double the distance from a point light source, the intensity of light received at that distance decreases to a quarter of the original intensity.

To put it in simpler terms, if you have a light bulb that emits a certain amount of light, and you move away from that bulb, the amount of light you receive decreases rapidly. Specifically, the amount of light you receive decreases proportionally to the square of the distance you move away from the bulb.

This law is important in many areas of science and engineering, including optics, astronomy, and photography. For example, it helps us understand how light spreads out and gets dimmer as it travels through space, or how to properly set the exposure settings on a camera to capture a well-lit photograph.

Thus maybe 6 inches but no more than 12 inches

Here’s the reality of how strange light is as an object moves away from the source.
