Which term best describes the process that occurs when light passes through a lens? a. reflection b. refraction c. resonance d. polarization

A. Refraction, meaning the same thing...it just passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped this helps you :) 

Short Refraction

B. convex since the words are bigger
