Which law applies to situations in which light passes through matter?

AThe law of dispersion
BThe law of refraction
CThe law of reflection
DThe law of diffraction
Answer & Solution
Correct answer: B. The law of refraction
1. The second law covers transmission rather than bouncing. 2. The law of reflection applies where light bounces off matter. 3. The law of refraction applies where light passes through matter. 4. Together they cover both cases at a surface. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 25 'Geometric Optics', sections 25.1-25.7_
