why a ray of light doesn't deviate when passing from denser to rarer or vice versa , along the normal ?
Asked by Sushant Kumar | 2nd Jan, 2014, 12:47: PM
When light enters along the normal,
The angle of incidence is zero and hence angle of refraction is also zero.
Therefore light does not deviate when enters along the normal.
