showed that a thin film whose thickness is onequarter of the wavelength of light in the film serves as an antireflection coating when coated on glass. nfilm < nglass . If a quarter-wave thickness film with nfilm > nglass were used instead, would the film still serve as an antireflection coating? Explain.

Question

showed that a thin film whose thickness is onequarter of the wavelength of light in the film serves as an antireflection coating when coated on glass. n_film < n_glass . If a quarter-wave thickness film with n_film > n_glass were used instead, would the film still serve as an antireflection coating? Explain.
