Focal Point – Point where reflected or refracted rays meet & image is formed; Focal Length – Distance between center of mirror/lens and focal point
Spherical Aberration Because of the spherical shape of the mirror, the outer rays don’t reflect through the focal point:
We call this point the FOCAL POINT. To find this point you MUST use light from “infinity” Light from an “infinite” distance, most likely the sun.
