A periscope (Fig. 3) is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches or parades from behind a crowd of people. Suppose the objects is a distance p 1 = 1 . 80 m from the upper mirror and the centers of the two flat mirrors are separated by a distance h = 0 . 300 m . (a) If both the upper and lower mirrors form an angle 45 . 0 ° with the horizontal, i.e. α = β = 45 . 0 ° , what is the distance of the final image from the surface of the lower mirror? (b) If both the upper and lower mirrors form an angle α = β = 50 . 0 ° with the horizontal, i.e. , what is the distance of the final image from the surface of the lower mirror? (c) If the upper mirror forms an angle 45 . 0 ° with the horizontal and the lower mirror forms an angle 50 . 0 ° with the horizontal, i.e. α = 45 . 0 ° and β = 50 . 0 ° , what is the distance of the final image from the surface of the lower mirror? (d) If the upper mirror forms an angle 48 . 0 ° with the horizontal and the lower mirror forms an angle 45 . 0 ° with the horizontal, i.e. α = 48 . 0 ° and β = 45 . 0 ° , what is the distance of the final image from the surface of the lower mirror? t3_q13_phys2426.se1.docx
