Flashcards on Polarization of Light
Click on the flashcard to see the answer
What is the definition of polarization of light?
Polarization of light refers to the orientation of the electric field vector of light waves.
What are the two types of polarization?
Linear polarization and circular polarization.
How does linearly polarized light differ from unpolarized light?
Linearly polarized light has its electric field vibrations restricted to a single plane, while unpolarized light has random vibrations in all planes.
What is the principle behind polarized sunglasses?
Polarized sunglasses block horizontally polarized light, reducing glare and enhancing visibility.
How does a polarizer work?
A polarizer selectively transmits light waves that are oscillating in a specific direction while blocking the rest.
What is the main application of circularly polarized light?
Circularly polarized light is widely used in 3D cinema glasses to provide depth perception.
What is the effect of polarized light on photography?
Polarized filters for camera lenses reduce reflections and enhance color saturation in outdoor photography.
Why do polarized lenses make it difficult to see LCD screens?
Polarized lenses can block the light waves aligned with the LCD screen, causing the screen to appear dark or distorted.
What is the relationship between polarized light and birefringence?
Birefringence is the property of certain materials to split unpolarized light into two perpendicular polarized rays.
What is Brewster's angle?
Brewster's angle is the angle at which reflected light becomes fully polarized parallel to the boundary between two media.
How does polarized light phenomena occur in nature?
Polarized light phenomena in nature occur due to scattering and reflection of sunlight by various particles and surfaces.
What is the relationship between polarization and wavelength of light?
The polarization of light is independent of the wavelength. All wavelengths can be polarized.
What is the primary factor influencing the degree of polarization?
The angle of incidence of light on a surface is the primary factor influencing the degree of polarization.
How does the polarization of light affect 3D glasses technology?
The different polarization directions of each lens in 3D glasses help create the illusion of depth perception.
What is the difference between linear and circular polarization?
Linear polarization has the electric field vector oscillating in one plane, while circular polarization has it rotating in a circular pattern.

An angle at which light undergoes total internal reflection
An angle at which reflected light becomes fully polarized parallel to the boundary between two media
An angle at which light exhibits wave-particle duality
An angle at which light waves interfere constructively
Check Answers
