Radio waves pass through everywhere without interacting with each other and that enables us to hear different phone calls and radios without disturbance. However, we do hear some noise sometimes because different signals interfere with each other. How are both of the last two statements true (if they are)? Also, why do two light waves produce interference patterns? They're EM waves and they shouldn't interact, right?
