In the diagram, a ray of light travels through air and strikes a glass block. Part of the light is refracted, while part is reflected. The diagram labels two angles, $p$ and $q$. Which row identifies the angle of incidence and says whether total internal reflection takes place?
- Aangle of incidence: $p$; total internal reflection: no
- Bangle of incidence: $p$; total internal reflection: yes
- Cangle of incidence: $q$; total internal reflection: no
- Dangle of incidence: $q$; total internal reflection: yes
