The moon phases are described in terms of waxing and waning. When the moon is waxing, it means that the illuminated part is increasing, which occurs from new moon to full moon.

1. Waxing Phases: The term "wax-on to the right" indicates that the illuminated part of the moon is growing from the right side towards the left. This reflects the waxing crescent and waxing gibbous phases where increasing illumination happens as we approach the full moon.

2. Waning Phases: Conversely, "wax-off to the left" refers to the waning phases where the illumination decreases, starting from the right (full moon) to the left, leading back to the new moon.

Given this understanding, as the moon is becoming more full, it is indeed getting lighter from the right.

Final Answer

As the moon is becoming more full, it is getting lighter from the right.
