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