Question

Electron microscope gives better image than ordinary microscope because

• A. It uses electron having higher wavelength.
• B. It uses electron having lower wavelength.
• C. It uses ultraviolet radiations.
• D. It uses polarized light.

Answer 1

The correct option is B It uses electron having lower wavelength.

Electron microscope uses electron instead of photons (photons used in ordinary microscope), because electrons have a much shorter wavelength than photons, so allow to observe matter with atomic resolution.
Thus, the correct answer is (B) 'It uses electron having lower wavelength'.
