What happens to the energy in case of "destructive interference"?
Hi everyone,
I'll mention a few cases here.
1) In case of sound suppose we have two speakers. One gives off a certain sound and the other speaker gives off the exact inverted phase of the other speaker's sound, both with the samer power. No sound will be heard BUT my qs now where does the energy go? I suspect heat but am not sure.
2) Two water waves with exact opposite phases come across each other. Again they cancel each other out and the water is still. BUT where does the energy go here? Again heat or something else?
3) Two photons as far as I am aware would form a pair of elementary particles BUT here I'd like to know what happens if two photons of the SAME PHASE come together i.e. wht happens in case of CONstructive interference in case of photons? Does it turn into one single photon of higher energy?
Thankyou very much!
