Acell phone is placed 25 cm in front of a diverging lens with focal length of magnitude 20 cm. how far is the image of this phone from the lens?

-11.11 cm

Explanation:

The lens formula is defined as,

Here, f is the focal length, u is the distance of an object, v is the distance of image.

Given that, the diverging lens is given so according to sign convention of diverging less, u and f should be negative.

Given that, distance of an cell phone in front of a diverging lens is

And its focal length is .

Put the variables in lens formula. Therefore,

Therefore the image is formed of this phone at a distance of -11.11 cm from the lens.
