In what way are electron microscopes different from light microscopes in terms of their application in organic chemistry?
A
Light microscopes can achieve higher magnification than electron microscopes.
B
Light microscopes are more suitable for observing atomic structures.
C
Electron microscopes use beams of electrons to achieve higher resolution images.
D
Electron microscopes are used to observe living organic specimens.
Verified step by step guidance1
Understand the basic principle of how light microscopes work: they use visible light and lenses to magnify images of small objects, typically up to 1000-2000 times magnification.
Recognize the limitations of light microscopes: they cannot resolve structures smaller than about 200 nanometers due to the wavelength of visible light.
Learn how electron microscopes operate: they use beams of electrons instead of light, which have much shorter wavelengths, allowing for much higher resolution images.
Identify the applications of electron microscopes in organic chemistry: they are used to observe the fine details of cell structures, viruses, and large molecules, which are not visible with light microscopes.
Clarify the misconception about observing living specimens: electron microscopes require a vacuum and often involve sample preparation that is not suitable for living specimens, unlike light microscopes which can observe living cells.
