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`

Find the distance of the image from object O, formed by the combination of lenses in the figure : f=+10cmf=-10cn f=+30cm

what is the position and nature of image formed by lens combination shown in figure ? (f_(1),f_(2) are focal lengths)

what is the position and nature of image formed by lens combination shown in figure ? (f_(1),f_(2) are focal lengths)

Findout the position of the image formed by mirror u = + 30 cm, f = + 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 . For an object kept at a distance of 60 cm from the convex lens, the final image, formed by the combination , is a real image , at a distance of : |"Focal length" | = |"Focal length"| = 30 cm " " =120 cm

A combination of two thin lenses with focal lengths f_(1) and f_(2) respectively forms and image of distant object at distance 60cm when lenses are in contact. The position of this image shifts by 30 cm towards the combination when two lenses are separated by 10 cm . The corresponding values of f_(1) and f_(2) are

An object of height 4 cm is kept to the left of and on the axis of a converging lens offocal length 10cm at a distance of 15cm from lens. A plane mirror is placed inclined at 45^(@) to the lens axis, 10 cm to the right of the lens.Find the position and size of the image formed by the lens and mirror combination. Trace the path ofthe rays forming the image.
