Question

A "luminous" object is one like the Sun, that is a source of light. We understand that ALL Objects that are at some temperature are luminous. They emit infrared light that is beyond what we can see. The Sun is so hot that it also emits visible light. For now, assume that when we talk about a luminous object, that we mean one, like a flashlight or the Sun, that emits visible light. TRUE or FALSE: An object must be a luminous object in order for us to see it The answer is FALSE Now the Question IS.. In your answer above, you staked out a position about whether an object must be luminous or not for us to see it. In the sciences, such positions are often called hypotheses and are subject to experimental testing. Which of the following is the best experimental test that your position is correct? Check all that apply a. We can still see a flashlight even when it is off b. We cannot see the sun at night c. The sun produces shadows d. We can see a flashlight when it is on

Answer 1

A. We can still see a flashlight even when it is off.

Which means we can also see something that isnt even producing light. Or in other words- its a non luminous.
