Radio Waves and the Lorentz Force?
Why have you put V as the velocity of the wave? You're misunderstanding what the right hand rule represents.
The right hand rule, is a tool that is used to visually represent the cross product.
The ...

UV & IR radiation are mostly absorbed by water. Our eyes are predominantly water. If our eyes were made of another liquid, could we see slight UV/IR?
No. Over distances of order $1cm$ the absorption by water of near IR varies from about 1/1000 nearest the visible spectrum to near complete absorption at the low frequency end of near IR. For near UV ...

Apparent instantaneous EM propagation paradox in two concentric solenoids
If you think there's really a paradox, then in order to resolve it, you should ask yourself which assumptions are definitely true, so you can reconsider any remaining assumptions by process of ...

Apparent instantaneous EM propagation paradox in two concentric solenoids
If you are careful about all the delays, you will not find a paradox.
For example, you strongly energize a long solenoid by applying a voltage to the ends of the wires. Perhaps you close a switch. ...

Confusion in the showing EM wave exist from Maxwell equation
First of all, a general solution of a system of inhomogeneous linear equations (such the Maxwell equations with sources) can be always decomposed into a particular solution of the inhomogeneous ...

How is light as electromagnetic waves produced?
Light is always produced by excited electrons dropping back to a lower energy state and releasing photons. The excitation of the electrons can be caused by other electromagnetic waves or electric ...
