A) \[20{}^\circ \]
B) \[10{}^\circ \]
C) \[30{}^\circ \]
D) \[45{}^\circ \]
Correct Answer: A
Solution :
Given: \[{{\delta }_{m}}=10{}^\circ ,\,\mu =1.5\] For a thin prism of minimum deviation \[{{\delta }_{m}}=(\mu -1)A\] \[10{}^\circ =(1.5-1)A\] or \[A=\frac{10}{0.5}=20{}^\circ \]You need to login to perform this action.
