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 object is placed 12 cm to the left of a converging lens of focal length 8 cm . another converging lens of 6cm focal length is placed at a distance of 30 cm to the right of the first lens. The second lens will produce

An object is placed 12 cm to the left of a diverging lens of focal length -6.0 cm. A converging lens with a focal length of 12.0 cm is placed at a distance d to the right of the diverging lens. Find the distance d that corresponds to a final image at infinity.

An object is placed 12 cm to the left of a diverging lens of focal length -6.0 cm. A converging lens with a focal length of 12.0 cm is placed at a distance d to the right of the diverging lens. Find the distance d that corresponds to a final image at infinity.

An object is placed 80 cm from converging lens of focal length 25 cm. What is the nature of image?

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:

A converging lens has a focal length of 50cm. The power of this lens is :

An object is placed at a distance of 10cm 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 the path of the rays.
