Question

Both ends of a glass rod with index of refraction 1.60 are ground and polished to convex hemispherical surfaces. The radius of curvature at the left end is 6.00 cm , and the radius of curvature at the right end is 12.0 cm. The length of the rod between vertices is 40.0 cm . The object for the surface at the left end is an arrow that lies 23.0cm to the left of the vertex of this surface. The arrow is 1.50 tall mm and at right angles to the axis. a) What constitutes the object for the surface at the right end of the rod? b)What is the object distance from the surface? c)Is the object for this surface real or virtual?

Explanation / Answer

(a) The object of the right surface is the image formed by the left surface of the arrow.

(b) (1.00 / 23.0 cm) + (1.60 / x) = (1.60
