Question
In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (i) and in each case measure the values of the corresponding angle of refraction (r) and angle of emergence (e). On the basis of your observations your correct conclusion is:
-
i is more than 
r, but nearly equal to 
e
-
i is less than 
r, but nearly equal to 
e
-
i is more than 
e, but nearly equal to 
r
-
i is less than 
e, but nearly equal to 
r
Solution
A.
i is more than r, but nearly equal to e
