It is known that there are nerve connections between rods and cones in the retina, and the optic nerve that carries information to the brain has fewer connections to the brain than there are rods and cones.

This section describes some of the characteristics of the electromagnetic spectrum, including some of the conventional names given to electromagnetic waves over certain ranges of frequency.

In a plane mirror, the image will be the same size as the object and will be the same distance behind the mirror as the object is in front of the mirror. For a plane mirror, the image will be the same size as the object and will be the same distance behind the mirror as the object is in front of the mirror.

If the object is placed inside F (between F and the lens), the image will be on the same side of the lens as the object and it will be virtual, upright, and enlarged. For convex lenses, when the object is placed inside F, the image will be on the same side of the lens as the object and it will be virtual, upright, and enlarged.

The ray model of light describes the path of light as straight lines. The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; and (3) after being reflected from a mirror.

Snell’s Law may be stated that a ray of light bends in such a way that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
