The given lens is broken into four parts and rearranged as shown. If the initial focal length is \( f \), then after rearrangement the equivalent focal length is â
The given lens is broken into four parts and rearranged as shown. If the initial focal length is \( f \), then after rearrangement the equivalent focal length is â
Show Hint
When combining multiple lenses in series, the equivalent focal length is the reciprocal of the sum of the reciprocals of the individual focal lengths.
