Solution

Dear Student ,
$I f i_{1} = a n g l e o f i n c i d e n c e, i_{2} = a n g l e o f e m e r g e n c e, r_{1} = a n g l e o f r e f r a c t i o n . S o A n g l e o f p r i s m A = r_{1} + r_{2} T h e r e f o r e, a n g l e o f d e v i a t i o n, δ = (i_{1} + i_{2}) - (r_{1} + r_{2}) = (i_{1} + i_{2}) - A$
