what will be the focal length of a biconvex lens when it is divided into 4 and 2 pieces

Asked by Priya Rai 29th January 2011, 9:23 PM

Dear student,
As the equivalent focal length is directly proportional to the individual focal leengths of thin lenses, hence the resulting focal length also would be divided by 4 or 2.
If the answer does not satisfy your requirement, please get back to us by rephrasing the query.
Thanking you
