What is the appearance of metals when cut?

• A. Rough
• B. Shiny
• C. Dull
• D. Transparent

Answer: (B)

Metals typically exhibit a shiny appearance when cut due to their ability to reflect light. This luster is a result of the arrangement of atoms in a metal, which allows electrons to move freely and reflect light effectively. When a metal surface is freshly cut, the clean surface lacks oxidation or other surface contaminants, enhancing this shiny look. In contrast, other materials might have different appearances when cut. For instance, certain non-metals could appear dull or rough, and there are no known metals that exhibit transparency in the way the question implies. This characteristic of metals makes them distinct and easily recognizable in various applications, contributing to their often desirable aesthetic qualities in industrial and decorative uses.
