Which term describes a material that absorbs some wavelengths of light and transmits others?

• A. Selective Absorption
• B. Scintillation
• C. Scratch
• D. Scoop

Answer: (A)

Light interacts with a material by filtering the spectrum: some wavelengths are absorbed while others pass through. When a material absorbs certain parts of the spectrum and transmits others, the color we see is determined by the wavelengths that get through. This behavior is described by selective absorption, which is why a filter or gemstone takes on a specific color depending on which wavelengths are transmitted. Scintillation refers to light produced by a material after stimulation, not how it filters light. A scratch is a physical flaw, and scoop isn’t a term used to describe light interaction in this context.
