What is the Difference between plane of polarization and plane of vibration?
A plane including the direction of light propagation and the direction of electric field is called the "plane of vibration". The "plane of polarization" is a confinement of the electric/magnetic field vector to a given plane along the direction of propagation.
Difference between monochromatic and polarized light?
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.
What are polarized LEDs?
Polarized LEDs are light-emitting diodes that emit polarized light, meaning the light waves oscillate in a specific direction. This property can be advantageous in certain applications, such as displays and optical communication, where controlling the orientation of the light is important for performance.
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
Do polarized light consists of waves that vibrate in one direction only?
No, it isn't one direction, otherwise there would not have been vibration at all! In normal light, the electric field vibrates in planes which are perpendicular to the direction that the wave is moving. In polarised light, the electric field vibrates in only one plane which is perpendicular to the direction that the wave is moving.. (3 dimension has been considered in the answer; this is why plane(s) have been used in the answer)
Why light is characterized by electric vector although it also possesses the magnetic vector?
Light is characterized by its electric vector because its interactions with matter are primarily through the electric field. The magnetic field of light comes into play when dealing with certain materials or under specific conditions, such as in radio waves or at high frequencies, but in general, the electric field of light is more prominent in its interactions with matter.
What is elliptically polarised light?
Elliptically polarized light is a type of polarized light in which the electric field vector traces out an ellipse as the light wave propagates. It is a combination of linearly and circularly polarized light. Elliptical polarization can be characterized by the major and minor axes of the ellipse, as well as the orientation of the ellipse in space.
What is the Difference between plane of polarization and plane of vibration?
A plane including the direction of light propagation and the direction of electric field is called the "plane of vibration". The "plane of polarization" is a confinement of the electric/magnetic field vector to a given plane along the direction of propagation.

What is the light that passes through a polarizing filter?
Polarised light!
What is unpolarized light and how does it differ from polarized light?
Unpolarized light is light in which the electric field oscillates in all directions perpendicular to the direction of propagation. Polarized light, on the other hand, is light in which the electric field oscillates in a specific direction. The main difference between unpolarized and polarized light is the orientation of the electric field vibrations.
Is polarised light EM or not?
Yes, light is electromagnetic, whether it is polarized or not.
What is the relationship between the electric magnetic and wave velocity vectors?
The wave velocity vector is parallel to the cross product of the electric and magnetic vectors.If you crank a wood screw from the Electric-field direction to the Magnetic-field direction, the screw proceedsinto the wood in the direction of the wave's velocity vector.Here's another advanced and highly technical way to keep these directions straight ...Curl the fingers of your right hand in the direction FROM the electric vector TO the magnetic vector.Your right thumb (when extended) points in the direction of the waves velocity vector, and alsothe "Poynting Vector"; that's the direction in which the wave carries energy.
How are electromagnetic waves formed?
they are formed when a electric field and a magnetic field couple. When ever a charged particle undergoes an acceleration it emits electromagnetic radiation. Therefore when an electron 'jumps' from a high energy quantum state to a lower energy quantum state it produces em radiation of a particular frequency. And, more precisely, EM waves are created by accelerating a charge. An electron at rest (or cruising at constant speed) has a stable electric field radiating outwards (really inwards for negative charge). If the electron is accelerated, a ripple in the field radiates outward with the speed of light, with the strongest effect perpendicular to the electron's vector of acceleration and weakest part (zero) along the vector. The electric field fluctuation is in any plane along the vector, and the magnetic part is in the plane perpendicular to that and the vector.
How does an unpolarised light incident on a polaroid get polarised describe briefly with diagram of polarisation of light by reflection through a transparent medium?
When unpolarised light passes through a polaroid, the polaroid selectively absorbs the light waves oscillating in one direction, allowing only light waves oscillating in the perpendicular direction to pass through. This results in the unpolarised light becoming polarised, with its electric field vibrating in a single plane. The diagram for polarisation of light by reflection through a transparent medium involves light waves hitting the medium's surface at an angle, with only the waves oscillating in a specific direction being transmitted while the others are absorbed or reflected.
What is the difference between s and p polarized light?
S and p polarized light refer to the orientation of the electric field in a light wave. S polarized light has the electric field perpendicular to the surface it is reflecting off of, while p polarized light has the electric field parallel to the surface. This difference affects how the light interacts with surfaces and materials.
