How do you demagnify?

Demagnification can be achieved by using optical systems that reduce the size of an image. This often involves using lenses or mirrors with specific configurations, such as concave lenses, to decrease the apparent size of an object. Additionally, techniques like projection onto a smaller screen or utilizing a microscope with a higher numerical aperture can help achieve a demagnified view. Adjusting the distance between the object and the optical element also plays a crucial role in determining the level of demagnification.
