Questions & Step-by-Step Solutions
Two waves traveling in the same medium interfere constructively. What can be said about their phase difference?
Correct Answer: Phase difference is 0 or an integer multiple of 2π.
Step 1: Understand what interference means. Interference happens when two waves meet and combine their effects.
Step 2: Learn about constructive interference. This type of interference occurs when the waves add together to make a bigger wave.
Step 3: Know what phase difference is. Phase difference is the difference in the position of the waves at a given point in time, measured in radians.
Step 4: Identify the conditions for constructive interference. For constructive interference to happen, the phase difference must be 0 or a multiple of 2π (like 0, 2π, 4π, etc.).
Step 5: Conclude that if two waves interfere constructively, their phase difference is either 0 or an integer multiple of 2π.
