Q.

An electron microscope gives higher magnifications than an optical microscope because –

A. The velocity of electrons is smaller than that of light
B. The wavelength of electrons is smaller as compared to the wavelength of visible light
C. The electrons have more energy than the light particulars
D. The electron microscope uses more powerful lenses
Answer» B. The wavelength of electrons is smaller as compared to the wavelength of visible light
Explanation: An electron microscope is a microscope that uses a beam of acceleratedelectrons as a spume of illumination. Becalise the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, the electron microscope has a higher resolving power than a light microscope and can reveal the structure of smaller objects.
