283189 A parallel beam of light of intensity \(I_0\) is incident on a coated glass plate. If \(25 \%\) of the incident light is reflected from the upper surface and \(50 \%\) of light is reflected from the lower surface of the glass plate, the ratio of maximum to minimum intensity in the interference region of the reflected light is
