Question

The focal length of the converging lens above is 53 cm. If an object is located at d = 34 cm, where is the image in cm? Positive is to the right of the lens.

Answer 1

here,

the focal length , f= 53 cm

the object distance , do = 34 cm

let the image distance be di

using the lens formula

1/f = 1/di + 1/do

1/53 = 1/di +1/34

solving for di

di = - 94.8 cm

the image distnace is - 94.8 cm
