1The diagram shows a ray of light in air incident on a glass block.
Some of the light is refracted, and some of the light is reflected. Two angles p and q are marked on the diagram.
Which choice gives the angle of incidence and shows whether the ray undergoes total internal A reflection?
- AA angle of incidence = P; total internal reflection = no
- BB angle of incidence = P; total internal reflection = yes
- CC angle of incidence = Q; total internal reflection = no
- DD angle of incidence = Q; total internal reflection = yes
