An object is placed halfway between a planar (flat) mirror and a diverging lens with a focal length of -25cm. The distance between the mirror and the lens is 30cm. You view the image of the object's reflection in the planar mirror by looking through the lens. Where does this image appear? Light with a wavelength of 420nm in air is incident on a thin film of water (n=1.333) on top of a plate of glass (n=1.56). Calculate the two smallest thickness for the water film that will produce dark spots from reflection. Paragraph Add a File BI U v v ON + v 11. >>
