What is characteristic of an occulting light?
AI Explanation
The correct answer is D) 4 sec. flash, 2 sec. eclipse, 3 sec. flash, 2 sec. eclipse.
An occulting light is characterized by a pattern of flashes and eclipses, where the duration of the eclipse is longer than the duration of the flash. The pattern described in option D matches this definition, with a 4-second flash followed by a 2-second eclipse, and then a 3-second flash followed by a 2-second eclipse.
The other options are incorrect because they do not match the defining characteristic of an occulting light, which is the longer eclipse duration compared to the flash duration.
