Given below are two statements: One is labelled as Assertion A and the other is labeled as Reason R.
Assertion A: An electron microscope can achieve better resolving power than an optical microscope.
Reason R: The de-Brogilie’s wavelength of the electrons emitted from an electron gun is much less than wavelength of visible light.
In the light of the above statements, choose the correct answer from the options given below.

View answer and explanation

Correct option: B

Both A and R are true and R is the correct explanation of A.

Option B (Both A and R are true and R is the correct explanation of A) is correct because electron microscopes have better resolving power due to the shorter de Broglie wavelength of electrons compared to visible light.
