Question

Angle of prism = 60°
Angle of incidence =35°
Angle of emergence =45°
Angle of derivation=?

Pls answer this question step by step clearly I will mark u as brainliest

Answer 1

********************ANSWER*******************************

===========================================

ANGLE OF PRISM + ANGLE OF DEVIATION = ANGLE OF INCIDENT + ANGLE OF EMERGENCE

IE. 60 + D = 35 + 45

D = 80 - 60

D = 20
