A spherical [[Mirror]] is a type of [[Concave Mirror]] whose surface is a part of a sphere. For a given position of the center of the mirror $\vec C$ and a radius $r$. ![[Spherical Mirror .excalidraw.svg]] %%[[Spherical Mirror .excalidraw.md|🖋 Edit in Excalidraw]]%% >[!info] >On a spherical mirror, [[Quasi-Parallel]] [[Ray|rays]] of light will bounce off and will all eventually land in an aproximent area (highlighted in $\color{blue}blue$) called the [[Spherical Abberation]]. ### Mirror Equation $\huge \frac{1}{f} = \frac{1}{d_{O}} + \frac{1}{d_{i}} $ Where $f$ denotes the [[Focal Point|Focal Length]] of the mirror, $d_o$ is the 'object distance' between the object $O$ being reflected and the mirror, and $d_i$ is the 'image distance' which is the perceived distance of the mirrored image of $O$.. >[!tip] Important note on the [[Sign]] of distances >For *mirrors*, if light is coming from the left, anything from the front side of the mirror is considered **positive**, and anything on the right is considered **negative**. $\huge m = \frac{-d_{i}}{d_{O}} $ Where $m$ denotes the 'magnification' for that object. Note that in a spherical mirror (or any [[Concave Mirror]]), the reflection will seem to be inverted / upside down.
