Properties of image formed by converging lens

The object distance is smaller than the focal length of the convex lens (do < f)

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

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

– Upright

– The farther the object is from the convex lens, the greater the image size

– The farther the object is from the convex lens, the image farther away from the convex lens

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

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

– Real means the beam of light passes through the image

– Upright

– Enlarged

– The image is at a finite distance

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

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

– Real means the beam of light passes through the image

– Inverted

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

– The farther the object from the convex lens, the image is closer to the convex lens
