Concept explainers
(a) To determine:
The power of the contact lens required so that object far away are sharp.
Answer to Problem 13P
Solution:
Power of the contact lens is -1.17.
Explanation of Solution
Formula used:
Calculation:
The lens equation is given by,
For far point of the lens, let us consider the object is placed at infinite and image distance is negative. Thus,
(b) To determine:
The near point with the lens in place.
Answer to Problem 13P
Solution:
The near point is 35.33cm.
Explanation of Solution
Calculation:
For near point of the lens, image distance is considered as 25cm and it is negative. thus,
