# Properties of image formed by diverging lens

The object distance is smaller than the focal length of the concave lens (do > f)

Based on the calculation of the image formation by the concave lens, can be concluded that if the object distance (do) is smaller than the focal length (f), then the image properties are:

– Virtual means the beam of light does not pass through the image

– Upright

– The farther the object from the concave lens, the smaller the image size

– The farther the object from the concave lens, the farther the image from the concave lens

The object distance is greater than the focal length of the concave lens (do > f)

Based on the calculation of the image formation by the concave lens, can concluded that if the object distance (do) is greater than the focal length (f) then the image properties are:

– Virtual means the beam of light does not pass through the image

– Upright

– The farther the object from the concave lens, the smaller the image size

– The farther the object from the concave lens, the farther the image from the concave lens

The object distance is equal to the focal length of the concave lens (do = f)

Based on the calculation of the image formation of the concave lens, can concluded that if the object distance (do) equals the focal length (f) of the concave lens then the image properties are:

– Virtual means the beam of light does not pass through the image

– Upright

– Minimized (the image size ½ times the object size)

– The image distance is smaller than the object distance (the image distance ½ times smaller than the object distance)
