An upright object is placed at a distance of `40cm` in front of a convergent less of focal length `20cm`. A convergent mirror of focal length `10cm` is placed at a distance of `60cm` on the other side of the lens. The position and size of the final image will be:
A
`20cm` from the convergent mirror, same size as the object
B
`40 cm` from the convergent mirror same size as the object
C
`40cm` from the convergent lens, twice the size of the object
D
`20cm` from the convergent mirror, twice the size of the object
An upright object is placed at a distance of 40 cm in front of a convergent lens of focal length 20 cm. A convergent mirror of focal length 10 cm is placed at a distance of 60 cm on the other side of the lens. The position and size of the final image will be

An object is placed 12 cm to the left of a converging lens of focal length 8cm . Another converging lens of 6 cm focal lengh is placed at a distance of 30 cm to the right of the first lens. The second lens will produce
An illuminated object is placed at a distance of 20 cm from a converging lens of focal length 15 cm. The image obtained on the screen is:
An object is placed at a distance of 10cmm to the left on the axis of convex lens A of focal length 20cm. A second convex lens of focal length 10cm is placed coaxially to the right of the lens A at a distance of 5cm from A. Find the position of the final image and its magnification. Trace teh path of the rays.
