Electron beams can not be used to resolve images of objects. T/F? Correct Answer-False In all types of electron microscopy, electrons pass through the specimen. Correct Answer-False This type of light microscopy can be used to view very thin cells or flagella. It does that by using this property of light. Correct Answer-Dark field; Light scattering In this type of microscopy, light is delayed by passing through the sample and so objects look as if they are out of phase. It employs this ...

Microbiology Lab Midterm Questions and Answers Already Passed Compound microscope 1. Ocular-eyepiece lens (usually 10x) 2. Objective-nosepiece lenses (commonly 4x, 10x, 45x, and 100x) At what magnification do you use the oil immersion technique? 100x. Total Magnification = Magnification (Objective) x Magnification (Ocular) Important Parts of the Microscope Framework, Stage, and Lens System Framework Arm and base are the structural parts of the microscope which support the basic frame.
