Question: Two coherent sources emit waves of the same frequency. If the path difference is 0.5λ, what type of interference occurs?

Options:

Correct Answer: Constructive interference

Solution:

Constructive interference occurs when the path difference is an integer multiple of λ.

Two coherent sources emit waves of the same frequency. If the path difference is 0.5λ, what type of interference occurs?

Two coherent sources emit waves of the same frequency. If the path difference is 0.5λ, what type of interference occurs?

Step 1: Understand that coherent sources are two sources that emit waves of the same frequency and phase.
Step 2: Know that the symbol 'λ' represents the wavelength of the waves.
Step 3: Identify the path difference given in the question, which is 0.5λ.
Step 4: Recall that constructive interference occurs when the path difference is an integer multiple of λ (0λ, 1λ, 2λ, etc.).
Step 5: Since 0.5λ is not an integer multiple of λ, it does not meet the condition for constructive interference.
Step 6: Conclude that the type of interference that occurs with a path difference of 0.5λ is destructive interference.
