Physics-Properties of EM Waves
NEET Physics Properties of EM Waves Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): Gamma rays typically originate from atomic nuclei. | Reason (R): The wavelength of electromagnetic waves is often correlated with the characteristic size of the system that radiates.
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 NCERT context states that gamma radiation, with wavelengths ranging from 10^-14 m to 10^-15 m, typically originates from atomic nuclei, and this is correlated with the characteristic size of the system that radiates.
