Physics - Geometrical Optics Question with Solution | TestHub
A beam of light parallel to main optical axis falls on a converging lens of focal length . Behind the lens, coaxially at some distance , is a diverging lens of focal length . After passing through the diverging lens, the light focuses at a point ' A ' 5 cm behind the lens. The position of lenses are then interchanged :-

Solution:
\section*{Paragraph for Questions 7 and 8} The system contains a box of length . On the left end of the box, a plane mirror is placed and on the right hand a convex lens of focal length f is placed. An object is placed at a distance ' x ' from the plane mirror. Two images are formed for the system. One is direct refraction through the lens and other is after reflection from plane mirror and then refraction through the lens. The size of final images formed is same.
