Question

Draw a ray diagram to show refraction of light through a triangular glass prism and show angle of incidence and angle of deviation

Answer 1

Answer:

The angles of incidence and refraction at first face AB are ∠i and ∠r1. The angle of incidence at the second face AC is ∠r2 and the angle of emergence ∠e. δ is the angle between the emergent ray RS and incident ray PQ and is called the angle of deviation. In triangle TQR, the side QT has been produced outwards. Mark me as brainliest
