Question:
In glass prism and glass slab experiment which angle should be equal which angle and Angle r should be lesser or greater to Angle i and Angle e?
Answer:
In glass prism and glass slab experiment, angle of incidence (∠i) = angle of emergence (∠e)
And, angle of refraction (∠r) is less than angle of emergence (∠e), as the ray of light is passing from a rarer medium (air) to a denser medium (glass).
