Few days I am trying to learn more about electromagnetic waves, induction, electromagnetic spectrum... And how it's connected.
Here is what I understand now:
There is a lot of electromagnetic waves depend on their wavelength and frequency:
-infrared waves -visible -microwaves -radio waves ...
Electromagnetic wave is produced when we have oscillating electric and magnetic fields.
an oscillating electric field generates an oscillating magnetic field, and reverse.
First group of questions:
If we have oscillating electric or oscillating magnetic fields, dose it will create electromagnetic wave?
Could you on some simple example show me how is electromagnetic wave produced?
Also how we can know which wave will be created from electromagnetic spectrum?
Second group of question is about radio waves on example of wi-fi:
How radio wave carries data?
Also how that radio wave with data will transform to electrical signal and latter appear on our monitors?
