Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Select the best answer to the question:Explain why a scientist might choose to use an electron microscope rather than a light microscope.
A
The light microscope won’t show as much and it doesn’t make the picture as bigger as the electron microscope.
B
Electron microscope is better for a scientist to choose than a light microscope it uses electrons and not light.
C
An electron microscope gives a greater magnification and better resolution than a light microscope.
D
Scientists might need to choose the electron microscope because it is cheaper and easier than the light microscope.
Explanation: 

Detailed explanation-1: -Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Detailed explanation-2: -Ease of use in a laboratory-As light microscopes are generally less complex and less expensive, they are easier to use overall. Electron microscopes are larger and typically far more expensive and made up of complex components.

Detailed explanation-3: -As the wavelength of an electron can be up to 100, 000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects.

Detailed explanation-4: -Electron microscopes have much higher resolving power – the most powerful allow us to distinguish individual atoms.

Detailed explanation-5: -An electron microscope gives higher magnifications than an optical microscope because the wavelength of electrons used is smaller as compared to the wavelength of visible light.
