2. Consider the following diagram showing the crossing of two individual wave packets. Which phases represent total constructive interference? Which phases represent total destructive interference? a. Imagine that these two waves are water waves. If you were observing these waves on a pond, what would the water look like in phase E? What about in phase G? (Hint: Think about the sum of the two waves, and sketch what that sum would look like. Ask yourself, are the waves adding together, or canceling each other out?) b. Now imagine these two waves are light waves. In which phases would the interfering light waves appear brightest? In which phases would they appear the dimmest?
