Tools of Observation Initial studies of natural phenomena made with unaided senses, sight, smell, hearing, touch. However, our senses are limited: We can only detect a narrow section of the electromagnetic spectrum (between 750 nm and 400 nm) Resolution : For unaided human eye, the closest that two objects (or edges) can be together and still distinguished as separate entities ~0.1 mm Tools of observation allow us to extend our senses make us aware of natural phenomena invisible to our senses.

* Optical Microscopes A microscope is an instrument for viewing objects that are too small to be seen by the unaided eye. An optical microscope (also called a light microscope) uses light to project a magnified view of the object. Some examples of light microscopes
