CBSE Class 12-science Answered
the radii of curvature of both the surfaces of the lens are equal.If one of the surfaces is made plane by grinding,how will focal length and power change?

Expert Answer
the power would deecrease
as now it wont be able to converge light that much
and hence the focal lenght is increased
