Energy conservation in wave interference...
Hey folks,
Let's get right into the subject: we know that two waves of the same phase, frequency, type and wavelength traveling alongside each other interfere constructively and their intensity is 4 times that if it were one wave..
Now let's take it this way, suppose the two waves are traveling from a source parallel to each other, each wave carrying a specific amount of enrergy (E). Now you'd think that TWO of that wave would have an energy = 2E and hence assuming they fall on the same area the intensity is doubles, but it's 4 times now. How come??
