Question 7Navigation General

The correct answer is D) the period of light exceeds the period of darkness. An occulting light is a type of navigational light that alternates between periods of light and darkness, where the period of light is longer than the period of darkness. This is in contrast to other types of lights such as flashing lights, where the period of darkness exceeds the period of light, or fixed lights, which are constant. The other options are incorrect because A) describes an eclipsing light, B) describes a partially obscured light, and C) describes an isophase light, which are different types of navigational lights with different characteristics.
