That was a great explanation. For a polarized light why do we only talk about the electric field oscilating in one plane and not about the magetic field??
@PhysicsMadeEasy3 ай бұрын
According to Maxwell equations, a fluctuation of E in space, generates a fluctuation of B in time (and vice versa) perpendicular to the plane where the electric field fluctuates. Therefore, one implies the other. The origin is actually the electric field, the magnetic field being just a consequence of special relativity. When we talk about one, we imply the other. So for simplicity, when discussing linear polarization at the level of the video, it is not really necessary to discuss the magnetic field. the latter is implied.

@PhysicsMadeEasy2 жыл бұрын
Hi Lawrence. Soundwaves are longitudinal waves: the oscillations of the particles of air are parallel to that of the direction of their propagation. This is why soundwaves cannot be polarised. On the other hand, Light can be polarised because it is a transversal wave (the oscillation is perpendicular to that of the direction of propagation) . I hope this helps!

@@lawrencelam2333 I don't have a diagram, but maybe this will help: Imagine that you could trace a line along all the positions of an oscillating air particle. The particle oscillates from left to right, so that line would be horizontal. And it would be in the same direction as the propagation of the sound (the same direction than the longitudinal wave). Now place a polarizer in front of it, like in the video. The line you drew would cross the polarizer in one point only… The wave would just pass through unchanged, whatever the direction of the polariser’s axis…

Congratulations, you did a great job in explaining the matter, an the example with the rack was brilliant. I have a question, maybe you can enlighten me. Based on my current understanding, one lens of the polarizing 3D glasses will allow the vertical polarized light to pass and the other one will allow the horizontal one. I tried to put one above the other, hoping to filter out most of the light. However, this did not happen, how should I understand this ?
@PhysicsMadeEasy11 ай бұрын
If these are basic polarizing 3D glasses, all light should be stopped. But, maybe modern ones have a different way of working: there is some electronics in them that actually is synced to a signal that can make the polarisation axes of each lens flip in synchronicity with the movie...If this is true: the axis of pol between left and right may not necessarily be perpendicular in the absence of a sync signal. I am only speculating there... and I might be completely wrong, so you should check this by yourself on the web.

When EM wave are represented as a sine wave, for example, top peak represents the amplitude, what does the bottom peak represent
@PhysicsMadeEasy11 ай бұрын
Hi Aamir, you should find what you need to an answer that question in my video: "What are waves?". kzbin.info/www/bejne/gqC1g3holqxmd7ssi=alXB8FrPioNMT-hb The amplitude is the difference between the highest position (what you call the top peak - the max y of the sine curve- which is also called a 'crest'), and the equilibrium position (y = 0). For an EM wave, it represents the maximum value of the oscillating electric field strength (check my video, what is an EM Wave) The bottom peak (called a trough), is also a maximum displacement (in the negative direction this time). For an EM wave, it represents the maximum negative value of the electric field strength. Thus, it also also represents the amplitude.

A light wave is a elektromagnetic wave, if at one point light is polarized vertically, then what part of the elektromagnetic component are we talking about? Do we say its vrtically polarized because the magnetic component is oriented that way, and what happend to the elektro component, is that vertically also?
@PhysicsMadeEasy11 ай бұрын
When we are talking about a vertical polarisation axis, the term 'vertical' applies to the electric field: It means that only the vertical components of the electric fields will be allowed to pass through. The magnetic component of an EM wave emerges from the oscillation of the electric field. The oscillation of that magnetic field is in a plane perpendicular to that of the electric field oscillation. Therefore a vertical polarisation axis will allow the horizontal component of the magnetic field to pass through.
@kn0w0n310 ай бұрын
Are you saying that the polarizer is letting the electric component of the wave pass and blocking the magnetic component? Then, the magnetic component emerges after the electric component is past the polarizer? I'm basically trying to understand if the polarizer is temporarily removing one component of the wave as it passes through the polarizer.

@@kn0w0n3 Hi, In regards to the EM Wave itself, saying that the polariser acts directly on the MField, or that the MF is re-induced by the polarised EField is an equivalent statement.

So what about magnetic Field of Electromagnetic ray
@PhysicsMadeEasy11 ай бұрын
Hi Jaya, Within the scope of classical physics, Light is an oscillating electric field (See video what is an EM Wave). When an electric field oscillates, it automatically generates an oscillating magnetic field perpendicular to its oscillation plane. When you have one, you have the other. So to describe an EM wave, you just need to look at the electric field to describe it, because the magnetic field emerges naturally from it. The Magnetic components is only affected by a polariser because of how the electric field components are affected by that polariser... Example: if a polariser has a polarisation axis which is vertical, that means that only the vertical component of the oscillating electric field will be allowed to pass. This is equivalent to say that only the horizontal components of the magnetic field will be allowed to pass through.

Throw a stone in a pond. It creates circular ripples. The circle described by the crest of the wave is called the wavefront. Take a line perpendicular to the wavefront (in our case along the radius), that shows you the direction the wave is moving. This line is called the ray of the wave (like when we say a ray of light...). Does this help? Oh, and light is not something that traverses an EM field. It is an EM field that is oscillating and propagating in space. See this video for mroe info about that: kzbin.info/www/bejne/npyZZKiLndCNfpY

What I want to know is if you could actually see oscillations in the EM field, what would you see move? What would light propagating from a lightbulb look like in 3D space? In which direction would the medium physically oscillate? (It can't be like ripples on a pond, because we're missing a dimension, right?). Sorry if I've misunderstood, I really want to understand how light actually travels!

Hey, super smart guy One question Is a rainbow polarized light ? If so is it because the rain falls in one direction🤔
@PhysicsMadeEasy2 жыл бұрын
Hi Izzy, Light in a rainbow comes from the reflection of sunlight inside water drops (the sunlight enters the drop by the front of the drop, refracts, travels to the back of the drop, reflects at the interface between water and air, travels inside the drop again in the other direction and refracts again when it comes out.) For reflected light to be polarized, the incident light needs to arrive at the reflecting interface at a specific angle, Brewster’s angle. Light will arrive in a small range of angles at the reflecting surface: so some of the light of the rainbow will be polarized, but not all of it (usually 95% is actually polarized). The direction of the rain (the direction of the velocity of the droplets) has nothing to do with it, but the position of the sun might!
