To calculate the total magnification of a light microscope you must know the magnification of the _____ lenses. objective and ocular
What is a parfocal microscope? A parfocal microscope allows for specimens to remain in focus when changing between magnification
A microscope in which light rays pass directly through a specimen is a ________ microscope. bright field
A microscope that converts changes in the speed of light as it passes through an object into differences in brightness is a ________ microscope phase-contrast
Ultraviolet light is a key component of ____ microscope fluorescence microscopy
Diffraction occurs when light _____ passes through a small opening
Why is diffraction a problem for microscopy? The small size of higher-power lenses causes severe diffraction.
Electron microscopes use ________ to focus the electron beam. electromagnets
The best electron microscopes have a resolution of _____ nm 1 nm
Electron microscopes have a much better resolving power when compared to light microscopes because electrons _____ have shorter wavelengths than visible light rays

c) scanning tunneling electron microscope
Transmission electron microscopes have a maximum magnification of _____ 500,000 X
What is the function of Atomic force Microscope Atomic force Microscope allows 3 dimensional imaging and measurement of structures as small as nucleotides in DNA
What is resolution? Resolution refers to the ability of a lens to distinguish adjacent objects.
Light of ________ wavelength typically will result in ________ resolution. shorter, better
The ____ the wavelength, the greater the resolving power of the lens. The smaller the wavelength, the greater the resolving power of the lens.
