# is the angle of incidence equal to the angle of emergence in a glass prism(triangular) and in a glass prism?how are angle of prism and angle of deviation related to each other?

the angle of incidence is equal to angle of reflection ...............

Also, angle of incidence + angle of emergence = angle of deviation + angle at top of prism (means if AB is the base then the angle C)..

no, angle of incidence is not equal to angle of emergence in glass prism. but in case of minimum diviation , they are equal.

ang. of incidence + angle of emergence= angle of deviation + angle of the prism

No angle of incidence is not equal to angle of deviation,but for a certain angle of incidence,there will be minimum deviation.in this minimum deviation case,angle of incidence will be equal to angle of emergence!

angle of incident is 40 degree then angle of emergence = ?

the angle of incidence is 40 degree then angle of emergence =?

Yes, In a glass prism, ∠i =∠e. →∠i +∠e =∠δ +∠A
