1.2 Optical Devices
A technological item that helps us to see things much better, using light-related tools to improve focus, or magnify objects that we cannot see with the naked eye.
ex: (projector, television) glasses, magnifying glasses, microscopes, telescopes, binoculars

Microscopes:
Help us see objects very close up, such as bacteria, cells...
17th century: Antonie van Leeuwenhoek revolutionized the field of microbiology with the use of his microscopes.

Telescopes:
The invention of the telescope revolutionized the field of astronomy. The first telescope was invented in the 17th century in the Netherlands; however, the individual most commonly associated with the telescope was an Italian scientist called Galileo Galelei. He improved the refracting telescope in a way that transformed all previous ideas about space. |
