After tracing the path of a ray of light through a glass prism a student marked the angle of incidence ( $∠$ i), angle of refraction ( $∠$ r) angle of emergence ( $∠$ e) and the angle of deviation ( $∠$ D) as shown in the diagram. The correctly marked angles are:

Q. A student very cautiously traces the path of a ray through a glass slab for different values of the angle of incidence (∠i). He then measures the corresponding values of the angle of refraction (∠r) and the angle of emergence (∠e) for every value of the angle of incidence. On analyzing the measurements of these angles, his conclusion would be:
