What process absorbs some wavelengths of light and transmits others?

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

Answer: (B)

The main idea is how light interacts with a material by absorption and transmission. When a substance absorbs some wavelengths and lets others pass through, it does so selectively. That selective absorption removes certain colors from the spectrum, so the light that remains to be transmitted determines the color you perceive. In gemstones, impurities or the crystal structure cause this targeted absorption, making the stone appear colored because specific wavelengths are absorbed while others are transmitted. The other terms refer to phenomena or actions unrelated to how a material filters light—scintillation is light emitted after stimulation, while the remaining two items are not about light interaction at all.
