A) \[{{60}^{o}}\]
B) \[{{45}^{o}}\]
C) \[{{35}^{o}}\]
D) \[{{15}^{o}}\]
Correct Answer: B
Solution :
Let A be the angle of prism, then in minimum deviation position \[i=\frac{A={{\delta }_{m}}}{2}\] Given, \[A={{60}^{o}},\,{{\delta }_{m}}={{30}^{o}}\] \[\therefore \] \[i=\frac{{{60}^{o}}+{{30}^{o}}}{2}{{45}^{o}}\]You need to login to perform this action.
