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 would A point source of light is viewed through a plate of glass of thickness t and of refractive index 1.5. The source appears A 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 1 In 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 distance A 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. If after refle An object 1 cm long lies along the principal axis of a convex lens of focal length 15 cm , the centre of the object being at a distance of 20 cm from the lens. Therefore, the size Rays from an object immersed in water ( =1.33 ) traverse a spherical air bubble of radius R . If the object is located far away from the bubble, its image as seen by the observer l Full Ray Optics list All Olympiad workbook PYQs
