The waxing moon phase where one half of the lighted surface can be seen from Earth is called First Quarter.

Here's why:

* Waxing: This means the illuminated portion of the Moon is getting larger as seen from Earth.

* First Quarter: At this point, the Moon is exactly 90 degrees from the Sun in the sky. Therefore, we see exactly half of the illuminated side.
