Which statement describes the interaction of light with materials in general?

• A. Light only travels in straight lines and never changes
• B. Light can be transmitted, reflected, or absorbed depending on the material
• C. Light always slows to a stop in opaque objects
• D. Light cannot interact with transparent objects

Answer: (B)

Light interacts with materials in three common ways: transmission, reflection, and absorption. Which outcome occurs depends on the material’s properties and surface characteristics. Transparent materials mainly transmit light, so you can see through them. Reflective surfaces bounce light back, which is why they appear shiny or mirror-like. Absorptive materials take in light energy, often converting it to heat, and may appear dark or colored because they remove certain wavelengths from the light that would otherwise be visible. Sometimes light is partly transmitted and partly reflected or scattered, depending on the material and its surface. This is why different materials—glass, metal, cloth, or pigment—produce such varied appearances. So the general description that captures how light interacts with materials is that light can be transmitted, reflected, or absorbed depending on the material.
