Introduction
The orientation of oscillations in the plane perpendicular to a
transverse wave's direction of travel
Pre-Requisites:
Optics
Activity:
Polarized camera.
Real Life Question:
What is Polarization?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Polarization | A property of waves that can oscillate with more than one orientation. Electromagnetic waves, such as light, and gravitational waves exhibit polarization; sound waves in a gas or liquid do not have polarization because the medium vibrates only along the direction in which the waves are travelling. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Polarization Maintaining (PM) Fiber | A specialty fiber called the Polarization Maintaining (PM) Fiber intentionally creates consistent birefringence pattern along its length, prohibiting coupling between the two orthogonal polarization directions. |
Real life uses :
Polarizing filters are used in photography
Places to visit :
Photo studio.
Practical examples around us
| Examples | Explainations |
|---|---|
| Polarimeter | The polarization of light can be measured with a polarimeter. |
What you learn in Theory:
Polarization (also polarization) is a property of waves that can oscillate with more than one orientation.
What you learn in Practice:
The polarization of light is described by specifying the orientation of the wave's electric field at a point in space over one period of the oscillation.
