Polarization after reflection of a mirror

In summary, polarization after reflection of a mirror refers to the change in the orientation of light waves after they bounce off a reflective surface. This change is caused by the selective absorption and reflection of light waves by the mirror's surface molecules. A mirror causes polarization of light by absorbing and reflecting waves in a specific pattern, resulting in a polarized reflection. Horizontally and vertically polarized light have different orientations and produce different effects when reflected off a mirror. The polarization of light can be changed after reflection through various means. Polarization after reflection is used in everyday life in applications such as sunglasses, photography, LCD screens, and scientific research.

Homework Statement


If a light beam is circularly polarized and then bounced off a mirror perpendicular to the optical axis, what is the new polarization.

My thought is, because circularly polarized light has basically 2 components behaving like waves, each of them is going to experience a phase shift by pi, so then the light will have the same polarization as it had before.

Sounds right to me. Generally, we use http://en.wikipedia.org/wiki/Wave_plate" to alter the polarization of a wave, and not mirrors.

1. What is polarization after reflection of a mirror?

Polarization after reflection of a mirror refers to the change in the orientation of light waves after they bounce off a reflective surface. This change in orientation is caused by the selective absorption and reflection of light waves by the mirror's surface molecules.

2. How does a mirror cause polarization of light?

A mirror is made up of tiny molecules that are arranged in a specific pattern. When unpolarized light waves hit the mirror's surface, some of the waves are absorbed by the molecules, while others are reflected. The reflected waves are polarized in a specific direction based on the orientation of the molecules, resulting in a polarized reflection of light.

3. What is the difference between horizontally and vertically polarized light?

Horizontally polarized light refers to light waves that are vibrating in a horizontal plane, while vertically polarized light refers to light waves that are vibrating in a vertical plane. These orientations are perpendicular to each other and produce different effects when reflected off a mirror.

4. Can the polarization of light be changed after reflection off a mirror?

Yes, the polarization of light can be changed after reflection off a mirror. This can occur if the mirror is made of a special material that can rotate the orientation of polarized light, or if the light is reflected off multiple mirrors at different angles.

5. How is polarization after reflection used in everyday life?

Polarization after reflection is used in many everyday applications, such as in sunglasses that reduce glare by blocking horizontally polarized light. It is also used in photography to control reflections and in LCD screens to produce images. Additionally, it is used in scientific research to study the properties of light and materials.
