Combination OF Lenses /Mirror|| Identification OF Lens/Image Nature

An small object is kept at 18cm from combination of a convex lens and plane mirror to get the image on object itself. Now the space between lens and mirror is filled with liquid of refractive index muL . Now we need to keep the object at 27cm to get the image on object. Find muL .

A thin convex lens of focal length 30 cm is placed in front of a plane mirror. An object is placed at a distance x from the lens (not in between lens and mirror ) so that its final image coincides with itself. Then, the value of x is

A concave mirror of focal length 20 cm and a convex lens of focal length 10 cm are kept with their optic axes parallel but separated by 0.5 mm as shown in the figure. The distance between the the lens and mirror in 10 cm. An object of height 3 mm is placed on the optic axis of lens at a distance between the lens and mirror is 10 cm. An object of height 3 mm is placed on the optic axis of lens at a distance 15 cm from the lens. Find the length of the image formed the mirror in mm.
