Expert Answer:

When light travels from one medium to another, its speed changes.
 
The angle of incidence and angle of refraction are related to refractive index as
 
n = sin i/sin r
 
Thus, sin r = sin i/n
 
Hence, if the refractive index of a medium is any value other than one, then r will have different value than i.
 
This indicates that the light has bent from its original direction.
