Consider a manual camera with a lens having a focal length of 5 cm . It is focused at infinity. For catching the picture of an object at a distance of 30 cm , one wouldA point source of light is viewed through a plate of glass of thickness t and of refractive index 1.5. The source appearsA small fish, 4 cm below the surface of a lake, is viewed through a thin converging lens of focal length 30 cm held 2 cm above the water surface. Refractive index of water is 1.33 Two identical lenses made of the same material of refractive index 1.5 have the focal length 12 cm . These lenses are kept in contact and immersed in a liquid of refractive index 1In case of real images formed by a thin convex lens, the linear magnification is (I) directly proportional to the image distance, (II) inversely proportional to the object distanceA horizontal ray of light passes through a prism of refractive index 1.5 and apex angle 4^ and then strikes a vertical plane mirror placed to the right of the prism.
