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.

Here we explore some basic cases where the location of the apparent source of light differs from the actual location of the source of the light.

Snell's Law: Describes the relationship between the angles of incidence and refraction, stating that the ratio of the sines of these angles is equal to the ratio of the indices of refraction of the two media.

For convex mirrors, the reflecting surface is on the outside of the sphere, placing the center of curvature and the focal point on the opposite side of the mirror from the object. Since the focal point is on the opposite side of the mirror from the object, the focal length is assigned a negative number.
