Eyepiece lens and Objective lens 1 of 17 What do both lenses do to the sample? Magnify it 2 of 17 Which lens is first to maginify the specimen? Objective lens 3 of 17 What does the eyepiece lens do? Magnifys it to make it clearer 4 of 17 Define Magnification How many times larger the image is that the actual size of the object being viewed 5 of 17 Define Resolution The ability to distinguish two objects that are close togther as seperate 6 of 17 How many Mirometers are in 100 nm 1 7 of 17 How many Micrometers in 1 mm 1000 8 of 17 How many Millimeters in 1 m 1000 9 of 17 How do Transmission Electron Microscopes work? A beam of electrons are transmitted through the specimen and focused to produce an image 10 of 17 How do Scanning Electron Microscopes work? A beam of electrons is sent across the surface of the specimen and the reflected electrons are collected back 11 of 17 What is maximum magnification of a Light Microscope? x2000 12 of 17 What is the resolving power of a Light Microscope? 200 nm 13 of 17 Which microscope is a vacuum required- LM or EM? Electron microscope 14 of 17 What is the magnification of a Electron Microscope? Over x500,000 15 of 17 What is the resolving power of a Transmission Electron Microscope? 0.5 nm 16 of 17 What is the resolving power of a Scanning Electron Microscope? 3-10 nm 17 of 17
