MCQ
Deviation of $5^o $ is observed from a prism whose angle is small and whose refractive index is $1.5$. The angle of prism is.......$^o$
- A$7.5$
- ✓$10$
- C$5$
- D$3.3$
✓
Answer
Correct option: B.
$10$
b
( b) $5 = (\mu - 1)A = (1.5 - 1)A \Rightarrow A = {10^o}$
( b) $5 = (\mu - 1)A = (1.5 - 1)A \Rightarrow A = {10^o}$
