Question: Solve the given problems by use of the sum of an infinite geometric series.
A double-pane window has a thin air space between two parallel panes of glass. If 90.0% of the incoming light is transmitted through a pane, and 10.0% is reflected, what percent of the light is transmitted through the second pane? See Fig. which illustrates one incident ray of light and its unlimited reflections and transmissions through the two panes of glass.
