Q. Double convex lenses are to be manufactured from a glass of refractive index1.55, With both faces of the same radius of curvature. What is the radius of curvature? Required if the focal length is to be 20cm?
Answer
The Refractive index of glass μ=1.55
Focal length of the double convex lens f=20cm
The Radius of curvature of one face of the lens = R1
The Radius of curvature of the other face of the lens = R2
The Radius of curvature of the double convex lens = R
R1= R and R2 = - R
The value of R is able to be calculated as
Therefore the radius of curvature of the double convex lens is 22cm.
