Match the proper entries from column-2 to column-1 using the codes given below the columns, if deviation in the Column–II is the magnitude of total deviation (between incident ray and finally refracted or reflected ray) to lie between 0º and 180º. Here n represents refractive index of medium. A. `{:(P,Q,R,S),(4,2,1,3):}`B. `{:(P,Q,R,S),(1,2,4,2):}`C. `{:(P,Q,R,S),(3,1,4,2):}`D. `{:(P,Q,R,S),(2,4,1,3):}` |

Answer» `C=sin^(-1)((1)/(2//1))=30^(@)` for `i=37` TIR so, `delta=pi-2(37^(@))=104^(@)` `i=25` refraction `deltalt(pi)/(2)-C` `i=45^(@)` TIR so, `delta=pi-2((pi)/(4))=90^(@)` by applying snells law for prism `i=90` `r_(1)=30," "r_(2)=30` `e=45` `delta=90+45-60=75^(@)` |
