Raising a Glass
The bottom of this glass acts as a concave diverging lens when used to view an object. In this photo, the object is a hand which is held approximately six inches above the bottom of the glass yet the hand appears much farther away than 6 inches. Concave diverging lenses have the same characteristics no matter how far the object is away from the lens: the image is always virtual, upright, and de-magnified. The hand is de-magnified by the lens-like-properties of the glass. The lens distorts the image because the light rays that pass through the lens are brought to a focus in front of the lens instead of behind is where the image is actually located.
