Question 1
Question
The 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?
Image:
Q1 (binary/octet-stream)
Answer
