Study Notes
Polarization of Light
- Light can be polarized, which means it can vibrate in a single plane or direction.
- A polarizer is a device that allows waves to pass through in only one direction, demonstrating that light is a transverse wave.
- When a wave is sent through a polarizer, only the components in the same direction as the polarizer can pass through, while the other components are blocked.
Characteristics of Polarization
- Unpolarized light, such as light from the Sun, can be polarized by a polarizer, limiting its vibration to a single plane.
- When a polarized light wave passes through a second polarizer oriented at a right angle (crossed polarizers), the light is completely blocked, resulting in absolute darkness.
Polarizer Alignment
- When two polarizers are aligned in the same direction, light can pass through both, indicating that they are polarizing in the same way.
- If the polarizers are oriented at a right angle (crossed), no light can pass through, resulting in zero transmittance.
