So we study the natural laws of light waves in order to better understand. Absolute threshold - absolute threshold is the smallest possible stimulus our bodies can perceive. FOR EXAMPLE: if a light was just on the edge of our absolute threshold, then if it were made just the tiniest bit dimmer we would not be able to perceive it at all.
