A) 0.1V
B) 1.5V
C) 0.75V
D) zero
Correct Answer: C
Solution :
For a thin prism [A assumed to be small] \[\operatorname{i}+e=A+\delta \] \[\operatorname{Since} it emerges normally \therefore e = 0\] \[i=A+\delta \] (i) for minimum deviation \[\delta =\left( \mu -1 \right)A\] (ii) Using (i) and (ii) \[\operatorname{i} = A + \left( \mu -1 \right)A\] \[\operatorname{i} = A +\mu A - A\] \[1 =\mu A\]You need to login to perform this action.
