1.	A student performs the experiment on tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. He measures the angle of incidence anglei, angle of refraction angler and angle of emergence angle e for all his observations. He would find that in all cases :
Answer» `angle i` is more than `angle r` but (nearly) equal to `angle e` `angle i` is LESS than `angle r` but (nearly) equal to `angle e` `angle i` is more than `angle e` but (nearly) equal to `angle r` `angle i` is less than `angle e` but (nearly) equal to `angle r` SOLUTION :NA
