ADispersion and absorption
BReflection and dispersion
CRefraction and diffusion
DReflection and refraction
Answer & Solution
Correct answer: D. Reflection and refraction
1. Two laws govern how light changes direction when it interacts with matter.
2. The law of reflection covers situations in which light bounces off matter.
3. The law of refraction covers situations in which light passes through matter.
4. Dispersion and diffusion are consequences of these two laws rather than separate governing laws.
