Jack is camping in the woods. while stargazing, he notices a very faint light in the distance. the light is so faint that he can barely see it, and his friend has not noticed it at all. the light is right at the threshold.

Absolute

Explanation:

In psychology of perception, the concept of absolute threshold refers to the lowest level of a stimulus that would make it detectable by the human senses. In other words, is the lowest level of something that a person would perceive.

In this example, Jack notices a very faint light that he can barely sees (but he can see it anyway) while his friend doesn't notice it. We can see that the light was so weak it was hardly detectable by the eyes (and Jack's friend didn't notice it). Since the light was so weak, we can say that it was at the lowest level that would make it detectable by humans and therefore is at the absolute threshold.
