Understanding Microscopes

Light microscope = Ideal for viewing live specimens Electron microscope = Provides higher magnification and resolution

Magnification = Enlarges the appearance of an object Resolution = Ability to distinguish between two close objects Light microscope = Lower resolution than electron microscopes Electron microscope = Shows images in black and white

Fine focus = Used for precise focusing Coarse focus = Used for initial focusing Eyepiece lens = Contains a magnification of 10x Diaphragm = Regulates the amount of light entering the microscope

<p>Cost = Electron microscopes are more expensive Image quality = Electron microscopes provide higher resolution Color observation = Light microscopes allow viewing in color Specimen requirement = Electron microscopes require dead specimens</p> Signup and view all the answers

<p>Magnification = Total magnification can be calculated by multiplying the eyepiece and objective lens Actual size = Can be determined from the magnification and image size Standard form = A number between 1-9 multiplied by $10^?$ Calculation examples = Used for determining how many times an object has been magnified</p> Signup and view all the answers
