Question

Electron microscope has more resolving power than optical microscope. We can control the energy of electron.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (B)

If both assertion and reason are true but reason is not the correct explanation of assertion.

Answer 2

Resolving Power, R.P. $\propto\frac{1}{\lambda}$. An electron microscope has extremely high resolving power because the electronic beams have wavelength 105 times shorter than visible light.
