An object is placed 30.5 cmcm from a +5.0-DD lens. A spherical mirror with focal length 25 cmcm is placed 75 cmcm behind the lens. Note that the mirror reflects light back through the lens. Find the distance from original object to the final image, measured from the object toward the lens. Enter negative value if the object is between the image and the mirror and positive value otherwise
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.

Find the distance from original object to the final image, measured from the object toward the lens. Enter negative value if the object is between the image and the mirror and positive value otherwise.
