Solution
When light ray goes from denser to rarer medium (i.e. more μ to less μ) it deviates away from the normal
On the other hand, if light ray goes from rarer to denser medium (i.e. less μ to more μ) it bends towards the normal.
the refracted ray is on the same side of the normal as the incident ray, which never happens in case of any refraction. So it is incorrect.
