comment Working of a crystal radio
I still don't get why does the coil store only a specific voltage from some specific frequency. Does it depend on the length of coil, i.e. length is proportional to voltage? Therefore, It can be assumed that different frequencies produce different voltages,

comment How does radio receives signal from particular station?
When thousands of radio waves hit the antenna at the same time, a voltage is passed down the radio antenna, so does it know the frequency from the power of voltage?

comment What makes up a resonator of radio?
How does the resonant circuit respond to one specific frequency from thousands of frequencies hitting the antenna and also amplifies it?

comment How much electric charge do electromagnetic waves carry?
Can I assume that the magnetic field is converted to electric field which causes the electrons to move? Or is the electric field in EMF itself? I think I'm assuming the electric field to be the source of electric charge which is what causing the confusion.

comment How much electric charge do electromagnetic waves carry?
It just makes me wonder how does radio translates them into a message, isn't that the electrons flow through in antenna at receiver end?
