People use microscopes to view objects that are too small to see with the naked eye. Microscope hardware is usually made up of glass lenses, metal or plastic frames for component housing, and an eyepiece. Electron microscopes use electron beams and sensors to create images on a monitor for viewing extremely small objects.

Telescopes enable people to see objects far away. Lenses and mirrors work together to magnify objects for viewing. A radio telescope is actually an antenna designed to receive radio waves from astronomical radio sources in space.
