MCQ
Yellow light is refracted through a prism producing minimum deviation. If $i_1$ and $i_2$ denote the angle of incidence and emergence for the prism, then ..........
- ✓$i_1=i_2$
- B$i_1 > i_2$
- C$i_1 < i_2$
- D$i_1+i_2=90$

Answer
Correct option: A.
$i_1=i_2$
a
(a)
(a)
At angle of minimum deviation angle of emergence of prism is same as angle of incidence.
