    Atom Vibration in Solids: 3D Pattern

    I just wantedhow the atoms vibrate in solids. I do not want to know the reason of their vibration (I know it). I just want to know their pattern of vibration. Some people say that they vibrate by undergoing a to and fro motion. But I do not think it is true because the objects are three...

    EM Waves: Why No Electromagnetic Wave Production?

    @BILL K I'm not talking about Earth's magnetic field. What I'm talking about is the production of EM waves due to centripetal acceleration. And please explain how accelerating charges do not always produce em waves...

    EM Waves: Why No Electromagnetic Wave Production?

    take it like this. There is an observer with a charge on earth. He should see EM waves being produced as the Earth is rotating (and revolving of course). But he doesn't see any EM waves until the charge accelerates with respect to him. This thing is confusing me a lot. Please Help.

    EM Waves: Why No Electromagnetic Wave Production?

    We all know that Earth is rotating. So every particle on it is accelerating. So all the charges present on it are accelerating. So why there is no production of elecrtomagnetic waves by them? (As accelerating charges produce EM waves)

    Which component of an electromagnetic wave is responsible for visible effect?

    @claude bile Hmm... strange! In my school syllabus, it is told to us that electric field is primarily responsible for polarisation. Anyways, then could you please sum up all this to give a final answer to my original question?

    Why some metals have 0 resistance at 0 kelvin

    Hey someone please explain why some metals have 0 resistance at 0 kelvin (absolute zero). Please explain the complete mechanism properly.

    Which component of an electromagnetic wave is responsible for visible effect?

    Sorry I meant E=Bc. @naty1 Look there has to be something that is responsible for the visibility effect. And now I think that Electric field is responsible because of its larger magnitude. ( It will have a greater impact on the photographic plate).

    Which component of an electromagnetic wave is responsible for visible effect?

    I think I disagree. The fields can ofcourse not be isolated, but I think that both fields play separate roles. For example, take the case of polarisation. Mainly electric field is responsible for polarisation because of its larger amplitude (E=B/c).

    Which component of an electromagnetic wave is responsible for visible effect?

    All right everyone, this was my own question and so I don't have any reference. Firstly, let us think about this in a different manner. I now believe my previous reasoning was incorrect. Let us modify the question to avoid any biological explanation (it's physicsforums after all:)). Consider the...

    Which component of an electromagnetic wave is responsible for visible effect?

    Thank you clem! I think you are right. @nasu I think I can explain. The objects are visible to us because of currents induced in our retina. As the magnetic field is responsible for induction of current, it is the magnetic field that is responsible for the visibility of stuff around us.

    What is SPEED OF LIGHT With Respect to an Observer?

    Sorry. Actually, this all error was because of editing the original diagram. I'm now explaining to you , the whole experiment from scratch. There is a room with suspended colloidal particles. There is no air. There are three points P, Q, R. They form a right triangle right angled at Q. The...

    What is SPEED OF LIGHT With Respect to an Observer?

    Actually, it has a lot to do with my example. In my earlier example on the line QR, assume there are more equidistant points A, B, C in between Q & R. Then although the light is traveling in vaccum, when the light hits the colloidal particle at A, a wavefront from A reaches P in time T1. When...

    What is SPEED OF LIGHT With Respect to an Observer?

    Well, sir, in relativity, the thing that matters is 'what appears'. If an observer starts calculating everything, he will overcome effects such as time dilation (which occurs at high speeds). And I know that the speed of light in VACCUM is same for all observers. But the colloidal particles can...
