Question

If a converging lens forms a real, inverted image 24.0 cm to the right of the lens when the object is placed 48.0 cm to the left of a lens, determine the focal length of the lens

Answer 1

f = 16 cm

Step-by-step explanation:

If a converging lens forms a real, inverted image 24.0 cm to the right of the lens when the object is placed 48.0 cm to the left of a lens, the focal length of the lens is 16 cm.

Answer 2

Focal length, f = 16 cm

Step-by-step explanation:

Image distance, v = 24 cm

Object distance, u = -48 cm

We need to find the focal length of the lens. It can be determined using the lens formula as :

`(1)/(v)-(1)/(u)=(1)/(f)`

`(1)/(24\ cm)-(1)/((-48\ cm))=(1)/(f)`

f = 16 cm

So, the focal length of the converging lens is 16 cm. Hence, this is the required solution.
