###### PLAY
The location where all parallel incident rays reflect through or converge
Focal Point
An imaginary straight line that runs through the center of curvature and focal point
Principal Axis
An item placed in front of the mirror
Object

As an object is moved further away from the focal point of a concave mirror, what happens to the image?
The image gets smaller and gets closer to the mirror.
