Question
A narrow monochromatic beam of light of intensity I is incident on a glass plate A as shown below in the figure


Another identical glass plate B is kept close to A  and parallel to it. Each glass plate reflects 25% of the light intensity incident on it and transmits the remaining.Find the ratio of maximum and minimum intensities in the interference pattern formed by the two beams obtained after reflection from each plate.
