What phase describes the moon's transition from a new moon to a full moon?

The transition of the moon from a new moon to a full moon is referred to as waxing. During the waxing phase, the visible illuminated portion of the moon increases from 0% at the new moon to 100% at the full moon. This process involves the moon moving in its orbit around the Earth, allowing more sunlight to reflect off its surface and become visible to us. As the moon grows fuller, the phases progressively transition from the new moon to the first quarter and then to the full moon, demonstrating the waxing nature of this phase.
