To answer this question, you need to understand the concept of light passing from one medium to another.
Option A) Refraction - This option is correct. Refraction is the bending of light when it passes from one medium to another, such as from air to water or from air to glass. This bending occurs due to the change in the speed of light as it enters a different medium.
Option B) Reflection - This option is incorrect. Reflection refers to the bouncing back of light when it encounters a surface, without any deviation.
Option C) Deviation - This option is incorrect. Deviation is a general term that can refer to any change or alteration. However, in the context of light passing from one medium to another, the specific term used is refraction.
Option D) Bifurcation - This option is incorrect. Bifurcation refers to the splitting or division of something into two branches or parts, which is not related to the process of light passing from one medium to another.
The correct answer is A) Refraction. This option is correct because it accurately describes the deviation of light when it passes from one medium to another.
