Does EM Wave induce emf in coil?

[Deadevil]

Hi!
Does electromagnetic waves induced emf or current in the coil or inductor due to faraday law as the magnetic field is continously changing in em wave?

Radio wave induce voltages in aerial wires etc.

That's how a TV or radio antenna works. Here's a circular-loop UHF TV antenna:

It means each & every em wave in the em spectrum will produce faradays law effect? Which in turn means visible light in em spectrum also induce current as other EM Wave induces? Am I Right?

Yes, electromagnetic waves can induce an emf (electromotive force) or current in a coil or inductor due to Faraday's law of induction. This law states that a changing magnetic field can induce an electric current in a conductor. In the case of electromagnetic waves, the changing magnetic field is created by the oscillating electric and magnetic fields of the wave. When these fields pass through a coil or inductor, they induce a current in the conductor. This is the basis for technologies such as wireless charging and radio communication, where electromagnetic waves are used to transfer energy and information through induction in coils and antennas.
