Question

What is the thickness of the non-reflecting film?​

Answer 1

Answer:

The thickness is generally chosen to be 1/4 of the wavelength of light in the middle of the visible spectrum, often green light. Thus the film will not give completely destructive interference for other colors, particularly for colors at the ends of the spectrum, red and violet.
