Answer 2

Answer:

Option C $\pi$ is correct , Reflection from a denser media causes a 180-degree phase shift,

Step-by-step explanation:

Reflection from a denser media causes a 180-degree phase shift, while reflection from a rarer medium has no effect.

Refraction does not result in a phase change. This is because the electric flow on both sides of the interface must be equal.

Because denser media reverse the direction, there is a phase difference due to light reflection from the surface of a denser material.
