The diagram depicts a ray of light travelling through air and striking a glass block. Part of the light is refracted, and part is reflected. Two angles $p$ and $q$ are labelled on the diagram. Which row states the angle of incidence and indicates whether the ray undergoes total internal reflection?
- 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
