The figure below shows a thin converging lens for which the radii of curvature of its surfaces have magnitudes of 9.44 cm (left side of the lens) and 11.2 cm (right side of the lens). The lens is in front of a concave spherical mirror with the radius of curvature R = 7.90 cm. Assume the focal points F₁ and F₂ of the lens are 5.00 cm from the center of the lens. (a) Determine the index of refraction of the lens material. (b) The lens and mirror are 20.0 cm apart, and an object is placed 8.22 cm to the left of the lens. Determine the position of the final image. Note that the light rays will first pass through the lens, then reflect off the mirror, then pass through the lens a second time in order for the eye to detect an image. distance cm location ---Select--- (c) Determine its magnification as seen by the eye in the figure.

Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
