When light travels through a medium and hits a boundary, which of the following is NOT an outcome?

When light travels through a medium and encounters a boundary, it can undergo several phenomena, including reflection, refraction, and absorption.

Reflection occurs when light bounces off the surface of the boundary, returning into the original medium. This process is described by the law of reflection, where the angle of incidence equals the angle of reflection.

Refraction takes place when light passes through the boundary and enters a different medium. This change in medium results in a change in the light's speed, leading to a change in direction, which is governed by Snell's law.

Absorption happens when light is absorbed by the medium it is traveling through, converting the light energy into other forms such as heat.

Polarization, on the other hand, is not an inherent outcome of the interaction between light and a boundary in the same way as reflection, refraction, and absorption. It refers to the orientation of light waves and can occur through specific interactions, such as scattering or through the use of polarizing filters, but it does not result directly from the light hitting a boundary. Therefore, it is the phenomenon that is not a direct outcome when light encounters a boundary with a medium.
