Finding the minimum thickness of a film for maximum interference - советы от нейросети

На тонкую пленку с показателем преломления 1,5 нормально падает свет с длиной волны 550 нм. Какой должна быть минимальная толщина пленки, чтобы в отраженном свете наблюдать максимум интерференции?

To determine the minimum thickness of a film in order to observe maximum interference in the reflected light, we can use the equation: nλ/2 = t, where n is the refractive index of the film, λ is the wavelength of the incident light, and t is the thickness of the film. In this case, n = 1.5 and λ = 550nm, so t = (1.5)(550nm)/2 = 412.5nm. Therefore, the minimum thickness of the film should be 412.5nm in order to observe maximum interference in the reflected light.
