A stamp collector uses a converging lens with focal length 28 cm to view a stamp 16 cm in front of the lens.(a) Where is the image located? (b) What is the magnification?
(a) To determine:
Location of image
Answer to Problem 51P
Solution:
Explanation of Solution
Given:
Object distance,
Focal length,
Formula used:
Lens equation,
u and v are lens to object and lens to image distances respectively, negative when opposite to optical path and positive when in the direction of optical path.
Magnification:
Calculation:
Image location can be calculated using lens formula.
Here value of u and f are given, i.e., u= -16cm and f=28cm. Thus substituting them in formula we get-
(b) To determine:
Magnification.
Answer to Problem 51P
Solution:
Explanation of Solution
Calculation:
Magnification can be calculated using the formula
Here value of v and u are given, i.e., v= -37.33cm and u=-16cm. Thus substituting them in formula we get-
