A student very cautiously traces the path of a ray through a glass slab for different values of the angle of incidence Zi 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 analysing these measurements of angles his conclusion would be A Zi Zr Ze B Zi Ze Zr C Zi r Ze D Zi Ze r
