AI Thread Summary
The discussion emphasizes the importance of self-research before seeking answers from others. Participants encourage users to utilize resources like Google and Wikipedia to find foundational information. A specific question about why only certain fractions of wavelengths reflect electromagnetic radiation is raised, indicating a desire for clarification on this topic. The forum promotes a learning approach where individuals are urged to ask specific questions if they encounter difficulties. Engaging in independent research is seen as a valuable way to enhance understanding.

hi all, could someone please explain how the above work? Thanks in advance.
 
Physics news on Phys.org
yes I could :)

but what research have you done for yourself so far ?
have you even tried to type your topic title into google ?

the first google hit was a wiki link that told you everything you would probably want to know


on Physics Forum, we try to encourage people to learn to do research, rather than have some one just spout out all the answers. You will learn much more that way :)
If there is something specific in that wiki link you don't understand, then ask specific questions


regards
Dave
 
yes why do only certain fractions of wavelenths reflect em radiation?
 
and sorry i thought if someone explained it in a summarized fashion it would help.
 
so why those fractions of the wavelenth?
 
Thread 'Gauss' law seems to imply instantaneous electric field propagation'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Thread 'A scenario of non-uniform circular motion'
(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...
Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
