why do EM waves from different TV stations not interfere with each other ?
1.Radio stations are spread out across different frequencies in
an area. For you to successfully cancel out one station with
another, you would need them to be the same frequency so that the
crests and troughs of one wave always coincides with
another.
2.When you receive radio signals on a receiver, you filter out the signals except for a small bandwidth centered around the desired carrier signal. So it doesn't matter that you may be receiving signals from twenty different stations since you can filter out all but a desired frequency.
