Question

16. A pair of red lights mounted 1 meter apart are far enough away that they are barely resolvable as two sources. A similar pair of blue lights (also 1 meter apart) is also mounted far enough away as to be barely resolvable. Which pair of sources is farthest from the observer

Answer 1

Light with the highest the frequency will be farther. Thus, since blue light is a higher frequency than red it would be farther away
