Absolute threshold
the absolute threshold is the smallest amount of a stimulus that a person can detect half the time.
imagine that researchers are conducting an experiment on light detection. In such an experiment, researchers my place participants in a dark room and then ask them to say when they can detect a light stimulus. The smallest amount of light stimulus that the participants can detect is known as the absolute threshold.
Electromagnetic radiation ranges from Gamma Rays, X-Rays, Ultraviolet, Visible Light, Infra-red, Microwaves, and Radio. Among them, only visible light has a wavelength that is compatible with the eye of a person. Moon on the other hand reflects the electromagnetic radiation coming from the sun which are visible light and infrared. Therefore, the correct answer to the question is Visible Light.
Answer:
Because they had to make sure the results were consistent.
