A plastic hemisphere has a radius of curvature of 8cm and an index of refraction of 1.6 . On the axis halfway between the plane surface and the spherical one (4cm from each ) is a small object O. The distance between the two images when viewed along the axis from the two sides of the hemisphere is approximately .

Two thin lenses are placed 5cm apart along the same axis and illuminated with a beam of light parallel to that axis. The first lens in the path of the beam is a converging lens of focal length 10cm whereas the second is a diverging lens of focal length 5cm. If the second lens if now moved toward the first, the emergent light
