Using a Diverging Lens to Obtain an Enlarged Image of an Object

When using a diverging lens, it is possible to obtain an enlarged image of an object under specific conditions.

Conditions for Obtaining an Enlarged Image: 1. Object Beyond the Focal Point: If the object is placed beyond the focal point of the diverging lens, an enlarged virtual image is formed on the same side as the object. This virtual image is erect and smaller than the object. - Source: - Source: - Source:
