If you live in the Northern Hemisphere, the left side of the moon is illuminated.
If you live in the Southern Hemisphere, the right side of the moon is illuminated.
Regardless of hemisphere, the western half of the moon is illuminated during the waning moon phases.
You would have to wait until after the moon is full. Then, the moon is in its waning phase and you can see it!
In the context of lunar phases, the waxing phase includes positions from the new moon (position 0) to the full moon (position 14), which corresponds to the first quarter (position 7) and the waxing gibbous. The waning phase follows, starting from the full moon (position 14) to the next new moon (position 28), including the last quarter (position 21) and the waning crescent.
The phase that occurs between the first quarter moon and the full moon is the waxing gibbous phase. During this phase, the illuminated portion of the moon continues to grow larger each night until it reaches full illumination.
The moon on February 1st, 2010 was in its waning gibbous phase, with approximately 93% of its visible surface illuminated. It would have appeared as a nearly full moon, but with a slight darkening on one side.
The moon on February 23, 2010, would have appeared as a waning gibbous phase, with more than half of its face illuminated. It would have been visible in the evening skies after sunset.

Waning Crescent.
Waning gibbous.
That would be Third Quarter.
The "waning gibbous" phase lasts from 2 days after the full to 6 days after the full.
If you see the Moon high in the sky in the evening, it is waxing. If you see the Moon high in the sky in the wee hours before dawn, it is waning.
In the context of lunar phases, the waxing phase includes positions from the new moon (position 0) to the full moon (position 14), which corresponds to the first quarter (position 7) and the waxing gibbous. The waning phase follows, starting from the full moon (position 14) to the next new moon (position 28), including the last quarter (position 21) and the waning crescent.
The moon phase on April 2nd varies each year. To determine the moon phase for a specific year, you would need to consult a lunar calendar or a moon phase tracking website.
In about 28 days, you would see a new moon phase after observing a waning crescent phase. The new moon occurs when the moon is positioned between the Earth and the Sun, with the side of the moon lit that faces away from Earth.
That would mean that the moon is in its waning phase. The light will be "swallowed" from the left to the right until it becomes a new moon, where it will begin is waxing phase. During the waxing phase, more and more of the moon is visible until it reaches the full moon, where the cycle repeats again.

No, ultraviolet light would not be reflected by a regular mirror, as most mirrors are designed to reflect visible light. Specialized mirrors designed to reflect ultraviolet light would be needed for reflection.
