Path difference = 0
Questions & Step-by-Step Solutions
What is the condition for constructive interference in two waves?
Step 1: Understand what constructive interference means. It happens when two waves combine to make a bigger wave.
Step 2: Know that waves can be described by their wavelength (λ), which is the distance between two peaks of the wave.
Step 3: Learn about path difference. This is the difference in distance that two waves travel to reach the same point.
Step 4: For constructive interference to occur, the path difference must be a whole number multiple of the wavelength. This means it can be 0λ, 1λ, 2λ, etc.
Step 5: The condition can be written as: path difference = nλ, where n is an integer (0, 1, 2, 3, ...).
