Question

A student traces the path of a ray of light through a rectangular glass slab for four different values of angle of incidence. He observes all possible precautions while fixing the pins and also while measuring different angles. On analysing the measurements he is likely to draw the following conclusion : (A) angle i = angle e < angle r (B) angle i = angle e > angle r (C) angle i > angle e > angle r (D) angle e > angle i > angle r

Answer 1

(B) Angle i = Angle e > Angle r is the correct conclusion.
