May you answer the question in the image attached below. Also, the answer is not 176 nm. I have tried using it, and it was marked as incorrect because "You may have confused the expressions of constructive and destructive reflection. To find the smallest thickness of the grease layer, recall the definition of the constructive reflection." Thank you.
