Illuminating the Moon’s glow: A simple demonstration of lunar reflection This clever demonstration perfectly illustrates how the Moon reflects sunlight, making it visible to us on Earth. Using a ball to represent the Moon and a light source for the Sun, we can easily visualize the lunar phases and understand why the Moon appears to change shape throughout its orbit. The Moon’s rocky surface acts like a cosmic mirror, bouncing sunlight back to Earth. This reflective property is key to our ability
