Question
Which of the following ray diagram show physically possible refraction
- (i)
- (ii)
- (iii)
- None of these
The correct answer is: (i)
When light ray goes from denser to rarer medium (i.e. more 
to less ) it deviates away from the normal while if light ray goes from rarer to denser medium (i.e. less more ) it bend towards the normal.
This property is satisfying by the ray diagram (i) only.
