When a ray of light travelling in an optically denser medium, emerges into an optically Iess denser medium, It:
The correct option is B deviates away from normal
Explanation for the correct option(s):
B: deviates away from normal
- When a ray of light goes from a denser medium to a less denser medium, it always bends away from the normal, which is drawn at the point of incident.
- The angle of incidence is always smaller than the angle of refraction in this case.
Explanation for the incorrect option(s):
A: deviates towards the normal
When a ray of light goes from a rarer or less denser medium to a denser medium, it bends towards the normal, which is drawn at the point of incident.
C: does not deviate
When an incident ray strikes normally at the point of incidence, it does not deviate from its course, i.e. no refraction occurs.
D: gets reflected
Refraction is the phenomenon that occurs when a ray of light deviates from its original path while travelling from one optical medium to another. So, no reflection will take place.
Hence, when a ray of light travelling in an optically denser medium, emerges into an optically Iess denser medium, it deviates away from normal.
