Lunar Phases and Synodic Month

Aileen Perez, an astrophysicist, explains the concept of the synodic month, which is the time it takes for the moon to return to the same phase, approximately 29.5 days. She describes the phases of the moon, including the new moon, first quarter, full moon, and third quarter, in relation to the sun's position. The video provides a detailed understanding of how the moon's phases are observed from Earth.
