Yes, that is correct. The Moon itself does not produce its own light. Instead, it reflects sunlight that falls upon its surface. When sunlight reaches the Moon, it interacts with the Moon's surface, and a portion of the sunlight gets reflected back toward Earth, allowing us to see the Moon illuminated. This reflected sunlight is what we perceive as the Moon's light.
The Moon's surface reflects sunlight because it consists of materials like rock and dust that are not able to emit light on their own. The amount of sunlight reflected by the Moon depends on various factors, such as the Moon's phase (which determines the angle at which sunlight strikes the surface) and the composition of the lunar soil.
During a full Moon, when the Moon appears as a complete circle, the Earth is positioned between the Sun and the Moon, and the entire illuminated side of the Moon faces us. In contrast, during a new Moon, the Moon is positioned between the Earth and the Sun, and the side of the Moon facing us is in shadow, making it appear dark.
So, in summary, the Moon does not generate its own light but instead reflects sunlight that reaches its surface, allowing us to observe it illuminated in various phases.
