Question 1475Navigation General

The correct answer is D) Intensity. The reason is that the Light List, which is a reference for identifying navigational lights, does not provide information about the intensity of the lights. The Light List specifies the other characteristics of the lights, such as the period, rhythm, and color, which can be used to positively identify each light. However, the intensity of a light can vary depending on factors such as weather conditions, distance, and the observer's position, and is not a reliable identifier listed in the Light List.
