A lens is made of a transparent material having an index of refraction of 1.50. One side of the lens is flat, and the other convex with a radius of curvature of 23.0 cm. (a) Find the focal length of the lens. (b) If an object is placed 110 cm in front of the lens, where will the image be located?
The concept used is of the relationship between the focal length of the combined lens with the radius of the curvature and the lens formulae , initially i draw the figure according to the condition given in the question and then fix the data in to the equation with appropriate sign , finally i deduced the value of the focal ength and the image distance.
