Final answer:
Properly overlapped beads will form a smooth surface, which allows light to transmit through without distinct reflections. An irregular surface, on the other hand, scatters light and can produce a blurred image.
Step-by-step explanation:
When viewed from the end, properly overlapped beads will form a smooth surface. This is because when the beads are overlapped correctly, they fit snugly against one another without leaving gaps or creating an uneven surface. As an example, if we imagine tiling a floor with perfectly round beads so that each bead touches the next without any space in-between, the result would be a smooth surface that feels even to the touch. On the other hand, if the beads were misaligned or differently sized, the surface would become irregular or bumpy, leading to an uneven feeling when touched.
The quality of the surface can also affect how light interacts with it. A smooth surface enables light to transmit through it, creating visibility without distinct reflections. In contrast, an irregular surface would scatter light in various directions, which could result in a blurred image or no clear transmission of light.
