Physics - Geometrical Optics Question with Solution | TestHub

A lens of focal length 20 cm is placed co axially with a concave mirror of radius of curvature 20 cm . A point objects ' P ' is placed at a distance of 30 cm from the lens as shown. Final image formed after two refractions from lens and one reflection by mirror is coincident with the object ' P ' itself. If x be maximum distance of mirror from object P and Y be minimum distance of mirror from the lens, then what is x in cm
