Reflection Of Light By Spherical Mirrors

The mirror equation relates the object distance , the image distance , and the focal length of a mirror: Where: - (focal length of the concave mirror, negative for concave mirrors), - (object distance, negative because the object is in front of the mirror), - is the image distance (to be determined). Rearranging the mirror equation: Substitute the known values: Thus: The negative sign indicates that the image is formed on the same side as the object, meaning it is a real and inverted image. The position of the image is from the mirror.
