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

A lens produces a virtual image between the object and the lens. Name the lens.

A linear object is placed on the axis of a lens. An image is formed by refraction in the lens. For all positions of the object on the axis of the lens, the positions of the image are always between the lens and the object. (i) Name the lens. (ii) Draw a ray diagram to show the formation of the image of an object placed in front of the lens at any position of your choice except infinity.

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.

A virtual, diminished image is formed when an object is placed between the optical centre and the principal focus of a lens. Draw a ray diagram to show the formation of the image with the above stated characteristics.

A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle, screen and the lens as under Position of candle = 12.0 cm Position of convex lens = 50.0 cm Position of the screen = 88.0 cm (i) What is the focal length of the convex lens ? (ii) Where will the image be formed if he shifts the candle towards the lens at a position of 31.0 cm . (iii) What will be the nature of the image formed if he further shifts the candle towards the lens ? (iv) Draw a ray diagram to show the formation of the image in case (iii) as said above.

An object is placed in front of a lens between its optical centre and the focus and forms a virtual, erect and diminished image. Draw a ray diagram to show the formation of the image with the above stated characteristics.

A converging lens is used to obtain an image of an object placed in front of it. The inverted image is formed between F_(2)and2F_(2) of the lens. Draw a ray diagram to illustrate the formation of the image obtained.

Copy and complete the ray diagram to show the formation of the image of the object AB

It is desired to obtain an erect image of an object, using concave mirror of focal length of 12 cm. (i) What should be the range of distance of an object placed in front of mirror ? (ii) Will the image be smaller or large than the object ? Draw a ray diagram to show the formation of image in this case. (iii) Where will the image of this object be, if it is placed 24 cm in front of the mirror ? Draw a ray diagram for this situation also to justify your answer. Show the positions of the pole, the principal focus and the centre of curvature in the above ray diagrams.

An object is kept 40 cm in front of a concave mirror of focal length of 20 cm. Find the position and nature of the image. Draw a ray diagram to show the formation of image in this case.
