5.
In a concave mirror, an object is placed at a distance \({ d }_{ 1 }\) from the focus and the real image is formed at a distance \({ d }_{ 2 }\) from the focus. then the focal length of the mirror is:
\(\sqrt { { d }_{ 1 }{ d }_{ 2 } } \)
\({ d }_{ 1 }{ d }_{ 2 }\)
\({ { (d }_{ 1 }{ /d }_{ 2 }) }^{ /2 }\)
\(\sqrt { { d }_{ 1 }{ /d }_{ 2 } } \)
