Qualitatively plot the intensity from n oscillators of the same amplitude and same angular velocity ω, with phase difference φ (constant), one from the other as a function of the difference φ for large n and for φ near 0.

  1. For which φ do we have the maximum intensity? (main maximum) and how much is that?
  2. For which φ do we have zero intensity? How many minima do we have between two main maximums?
  3. For which φ do we have local maximus (unlike the main ones)? How many maximums do we have between 2 main maximums? How much intensity in the secondary maximum compared to the main ones?
