QJEEM21Ph4ed1: JEE Main 2021 Physics - Class 12 JEEM21Ph4ed1 Solution: Given below are two statements : one is labeled as Assertion A…
Given below are two statements : one is labeled as Assertion A and the other is labelled as Reason R.
Assertion A : An electron microscope can achieve better resolving power than an optical microscope.
Reason R : The de Broglie'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 :
Assertion A : An electron microscope can achieve better resolving power than an optical microscope.
Reason R : The de Broglie'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 :
Multiple Choice Options
- A A is false but R is true.
- B Both A and R are true but R is NOT the correct explanation of A.
- C Both A and R are true and R is the correct explanation of A.
- D A is true but R is false.
Step-by-Step Verified Solution
Resolution limit ( ) =
Resolution power =
Resolution power
Since, wavelength of electron is much less than visible light, its resolving power will be much more.
Resolution power =
Resolution power
Since, wavelength of electron is much less than visible light, its resolving power will be much more.
