A transparent film (n = 1.30) is deposited on a glass lens (n = 1.50) to form a nonreflective coating. What is the minimum thickness that would minimize reflection of light with wavelength 480.0 nm in air? nm

Step 1
We know that the film is non-reflective, which means that the reflected waves from the top and bottom surfaces of the film interfere destructively. This occurs when the path difference between the two reflected waves is half the wavelength in the film. Show more…

A material having an index of refraction of 1.30 is used as an antireflective coating on a piece of glass $(n=1.50)$ . What should be the minimum thickness of this film in order to minimize reflection of $500-$ nm light?
