NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): De Broglie wavelength is significant for particles like electrons but negligible for macroscopic objects. | Reason (R): The wave nature of matter becomes apparent when the object's mass is small, and its momentum is low.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The De Broglie wavelength is significant for particles with small masses and momenta, like electrons, but negligible for macroscopic objects due to their larger masses, making the wave nature of matter undetectable.
