The position of fical image formed by the given lens combination from the third lens will be at a distance of f_1=+10cm,f_2=-10cm,f_3=+30

What is the position of image when an object is placed is at a distance of 10 cm from a convex lens of focal length 10 cm?

A convex lens of focal length 30 cm , a concave lens of focal length 120 cm , and a plane mirror are arranged as shown .

The same size images are formed by a convex lens when the object is placed at 20cm or at 10cm from the lens. The focal length of convex lens is ____ cm

When an object is placed at a distance of 36 cm from a convex lens, an image of the same size as the object is formed. What will be the nature of image formed when the object is formed. What will be the nature of image formed when the object is placed at a distance of: a) 10 cm from the lens? b) 20 cm from the lens?
