Question

Explain the following statement. :A ray of light emerging from a glass slab is slightly displaced to the left.​

Answer 1

Answer:

Refraction

Explanation:

A ray of light when emerging from a glass slab then it means light is changing its path through one denser medium(glass) to rarer medium(air). And we know that when light enter a medium from another medium its deviates with its original path depending upon the medium change is wrt (rarer to denser) or (denser to rarer). In this case the Refraction is due to medium change in denser to rarer in this the light bends away from the normal that's why it seem to deviates it path along left.
