In the diagram, a ray of light in air strikes a glass block. Part of the light is refracted and part of the light is reflected. Two angles, $p$ and $q$, are labelled on the diagram. Which row identifies the angle of incidence and states 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
