Young Brunette Girl Undresses In Front Of The Mirror

• Spherical concave and convex mirrors do not focus parallel rays to a single point due to spherical aberration. However, the ideal of focusing to a point is a commonly-used approximation. Parabolic reflectors resolve this, allowing incoming parallel rays (for example, light from a distant star) to be focused to a small spot; almost an ideal point. Parabolic reflectors are not suitable for imaging nearby objects because the light rays are not parallel.
Mirror image
If one looks in a mirror, one's image reverses (e.g., if one raises one's right hand, his left hand will appear to go up in the mirror.)
