Question
A biconcave/biconvex lens has ____ focal point(s) and ____ center(s) of curvature.
- 1,1
- 2,2
- 1,2
- 2,1
Hint:
Since there exists a curvature on both sides of the biconcave/biconvex lens, there will be around two focal points and also two centers of curvature.
The correct answer is: 2,2
A biconcave/biconvex lens has 2 focal point(s) and 2 center(s) of curvature.
- The center of curvature lies in the middle of the sphere.
- The focal point is the point where the refracted rays meet or seem like originated.
- A biconcave and biconvex lens has two focal points and two centers of curvature as the light rays can be passed from both directions.
