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

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

Resolving Power, R.P. 1 . An electron microscope has extremely high resolving power because the electronic beams have wavelength 10^5 times shorter than visible light.
