MCQ
A student traces the path of a ray of light through a rectangular glass slab for four different angles of incidence. He very cautiously measures the angle $f,$ angle $r$ and the angle $e$. On analysing his measurements, he is likely to draw the following conclusion :
- ✓$\angle\text{i} = \angle\text{e} > \angle\text{r}$
- B$\angle\text{i} > \angle\text{r} > \angle\text{e}$
- C$\angle\text{i} = \text{Zr} < \text{Ze}$
- D$\angle\text{i} = \angle\text{e}< \angle\text{r}$
