Consider a an equilateral prism ABC of glass `(mu= (3)/(2))` placed in water `(mu=(4)/(3))`

`{:("Column"I, "Column"II), ((A) FG "is parralel to" BC , (P) "Maximum deviation"),((B) i_(1) = 90^(@) , (Q) "Minimum deviation"), ((C) i_(1)= i_(2) = sin^(-1)((9)/(16)) , (R) TIR " will take place at surface" AC), ((D) EF "is perpendicular to" AB , (S) "No" TIR "will take place at surface" BC):}`

Answer

A, B, C, D

Explanation

At minimum deviation `i_(1) = i_(2)` , `EF||BC` , At maximum deviation `i_(1) = 90^(@) "or" i_(2) = 90^(@)`
For `i_(1) = 0, TIR` will not take place at `AC`
