The diagram illustrates a ray of light in air striking a glass block. Part of the light is refracted and part is reflected. The diagram labels two angles, $p$ and $q$. Which row identifies the angle of incidence and says whether total internal reflection occurs?
- 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
