An object placed 50 cm from a lens produces a virtual image at a distance of 10 cm in front of the lens. Draw a diagram to show the formation of image. Calculate focal length of the lens and magnification produced.

An object is placed 50 cm from a lens produces a virtual image at a distance of 10 cm in front of the lens. Draw a diagram to show the formation of image and calculate the focal length of the lens

A lens produces a virtual image between the object and the lens. Draw a ray diagram to show the formation of this image.

An object is placed at 50 cm from a lens produces a virtual image at a distance of 10 cm in front of the lens . What is the focal length of the lens ? Is it converging or diverging ?

An object is placed in front of a converging lens at a distance greater than twice the focal length of the lens. Draw a ray diagram to show the formation of the image.

An object kept at 60 cm from a lens gives a virtual image at 20 cm in front of the lens. What is the focal length of the lens ? It it a converging lens or diverging lens ? Also find the magnification produced.

An object placed 4 cm in front of a converging lens produces a real image 12 cm from the lens. a) What is the magnification of the image? b) What is the focal length of the lens? Draw a ray diagram to show the formation of image. Mark clearly F and 2F in the diagram.

An object is kept at 10 cm in front of a convex lens. Its image is formed on the screen at 15 cm from the lens. Calculate (1) the focal length of the lens (2) the magnification produced by the lens.

An object is kept at 10 cm in front of a convex lens . Its image is formed on the screen at 15 cm from the lens. Calculate (i) the focal length of the lens (ii) the magnification produced by the lens.

Calculate the focal length of a convex lens which produces a virtual image at a distance of 50 cm of an object placed 20 cm in front of it.
