What is the phase difference between two waves that interfere constructively?
Step 1: Understand what waves are. Waves can be thought of as repeating patterns, like ripples in water.
Step 2: Learn about interference. When two waves meet, they can either add together (constructive interference) or cancel each other out (destructive interference).
Step 3: Know what phase difference means. Phase difference is the difference in the position of the waves at a given time, measured in radians.
Step 4: Identify constructive interference. This happens when the peaks of one wave align with the peaks of another wave.
Step 5: Determine the phase difference for constructive interference. The phase difference must be an integer multiple of 2π (like 0, 2π, 4π, etc.).
Step 6: Conclude that a phase difference of 0 also means the waves are perfectly in sync, leading to constructive interference.
