Question

Resolution power of electron microscope is

• A. 0.1 mm
• B. $0.30\mu m$
• C. $0.2A^0$
• D. $0.2\mu m$

Answer 1

The correct option is C $0.2A^0$

Light microscopes have maximum resolving power of 1500X. The wavelength of light is 0.2$\mu$m. This property of light makes it impossible to go beyond this magnification. Electron microscopes have shorter wavelengths 0.2nm and can magnify an object several 100,000 times.
So, the correct answer is '0.2A${}^0$'.
