Ray Optics · Refraction
The sizes of the images of an object, formed by a thin lens are equal when the object is placed at two different positions 8 cm and 24 cm from the lens. The focal length of the lens is cm.
We corrected a printing error in the original paper
Source printed “The size of the images … are equal”.
