Concept explainers
The locations of the lens having focal length 16 cm between object and the image seperated by 86 cm for which sharp images are created.
Answer to Problem 58P
Solution:
The distances are of the lens from object creating sharp images at 86 cm are 21.25 cm and 64.75 cm
Explanation of Solution
Formula used:
Lens equation,
f, u and v are lens to focal, lens to object and lens to image distances repectively, negative when opposite to optical path and positive when in the direction of optical path.
Calculation:
As and
Thus,
We can write
Putting this in lens equation we get,
giving the quadratic equation-
Two solutions to this equation are
