TIR + HCV QUESTIONS

Find condition for TIR at surface 2 .

In the figure shown, mu_1gtmu_2. Find minimum value of i so that TIR never takes place at P.

If critical angle for TIR from medium to vacuum is 45 deg then velocity of light in medium

The refractive index of the material of a prism of refracting angle 45^@ is 1.6 for a certain monochromatic ray. What will be the minimum angle of incidence of this ray on the prism so that no TIR takes place as the ray comes out of the prism.

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):}
