Transcribed Image Text:Practice Problems -4
An object 2.50 cm high is placed 12.0 cm in front of a thin lens of focal length 3.0 cm.
Calculate (a) the image distance, (b) the magnification, and (c) the nature of the image.
(d) Check your answers by a graph.
A plano-convex lens is to be made of light flint glass of index 1.680. Calculate the
radius of curvature necessary to give the lens a power of 4.5 D.
A double-convex lens is to be made of glass having a refractive index of 1.580. If one
surface is to have twice the radius of the other and the focal length is to be +6.0 cm,
find the radii.
