1.	A student while doing the experiment on tracing the path of a ray of light passing through a rectangular glass slab measured the three angles marked as theta_(1), theta_(2) " and " theta_(3) in the figure. His measurements could be correct if he were to find :
Answer» `theta_(1) lt theta_(2) lt theta_(3)` `theta_(1) lt theta_(2) " but " theta_(1) = theta_(3)` `theta_(1) GT theta_(2) gt theta_(3)` `theta_(1) gt theta_(2) " but " theta_(2) = theta_(3)` Solution :NA
