In a displacement method the distance between the object and the screen is `70` cm and the focal length of the lens is `16` cm, find the separations of the magnified and diminished image position of the lens.

In the displacement method the distance between the object and the screen is 70 cm and the focal length of the lens is 16 cm, find the seperation of the magnified and diminished image position of the lens.

If the distance between the screen and object is 50 cm and the displacement of the lens is 10 cm,clculate the focal length of the lens.

In displacement method, the distance between object and screen is 96 cm. The ratio of length of two images formed by a convex lens placed between them is 4.84.

An object and the image obtained from the lens are as given above. If the distance between the object and the image is 36 cm and the magnification is -2, find the focal length of the lens and draw the ray diagram to show the position of the lens.

In displacement method, the distance between object and screen is 96cm. The ratio of lengths of two images formed by a converging lens placed between them is 4. Then,

In displacement method, the distance between object and screen is 96cm. The ratio of lengths of two images formed by a converging lens placed between them is 4. Then,

Find the distance of an object from a convex lens if image is two times magnified. Focal length of the lens is 10cm

Find the distance of an object from a convex lens if image is two times magnified. Focal length of the lens is 10cm

Find the distance of an object from a convex lens if image is two times magnified. Focal length of the lens is 10cm
