Physics-de Broglie Wavelength
NEET Physics de Broglie Wavelength Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The wave-like properties of particles are significant in the sub-atomic domain. | Reason (R): The de Broglie wavelength of macroscopic objects is too small to be measured.
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, but R is true.
Correct Answer
Option A
Detailed Explanation
The NCERT context explains that the de Broglie wavelength for macroscopic objects is extremely small, making wave properties unobservable, whereas in the sub-atomic domain, the wave nature is significant and measurable.
