| 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. |
