Answer 2

Compact discs:

In comparison to the technology required to create it, a compact disc appears to be a deceptively simple gadget.

Three layers of materials make up a CD:

• Polycarbonate plastic serves as the foundation layer.
• Over the polycarbonate material, a thin layer of aluminum is applied.
• Over the aluminum layer, a clear protective acrylic coating is applied.

In the production of compact discs, some producers utilize a silver or even gold layer instead of the aluminum layer.
