A diverging lens of focal length 15 cm forms an image of object placed at 30 cm from the lens.

The magnification of the lens is:

Expert Solution

we have,

focal length of diverging ( Concave ) lens

distance of object from the lens

As per the thin lens equation the relation between , and the distnace of the image from the lens will be given as,

Using and in above relation we get,

sign indicates that the image is formed on the same side as that the object,

So, the magnification of diverging lense will be given as,

using and we get the magnification of lense as,

A diverging lens of focal length -12.5 cm is placed 40.0 cm from a converging lens...

A diverging lens of focal length -12.5 cm is placed 40.0 cm from a converging lens of unknown focal length. A 15.2 cm tall erect object is placed 25.3 cm in front of the diverging lens which is to produce an image on a screen that is twice the size of the original object but inverted. A) Where should the screen be located to produce a clear image? Give the distance from the converging lens to the screen in cm. B)...
